What does it mean by charging and discharging a capacitor? What are the working principles of a capacitor? Charging a capacitor means the accumulation of charge over the plates of the capacitor, where discharging is a completely opposite process.

Suppose we have the circuit below, with capacitor C, voltage source V and a toggle switch. Consider the capacitor is discharged initially and the switch is open. The plate of the capacitor connected to the positive terminal provides electrons because the plate has comparatively more electrons than source positive terminal.

And plate connected to negative terminal absorb electron provided by the source negative terminal which has comparatively more electrons. This movement of the electrons is the charging current during the charging phase. As electron start moving between source terminals and capacitor plates, the capacitor starts storing charge. As charge stores, the voltage across the capacitor rises and the current between source and capacitor goes down.

At some stage in the time, the capacitor voltage and source voltage become equal and practically there is no current flowing. The below diagram shows the current flowing through the capacitor on the time plot. Current flowing at the time when the switch is closed, i. The below diagram shows the voltage across the capacitor and resistor on the time plot.

The following formulas are for finding the voltage across the capacitor and resistor at the time when the switch is closed i. The formula for finding instantaneous capacitor and resistor voltage is:. The current across the capacitor depends upon the change in voltage across the capacitor. If there is a changing voltage across it, will draw current but when a voltage is steady there will be no current through the capacitor.

Suppose the capacitor shown below is charged by a voltage source E, so the voltage across the capacitor will be raised to voltage E. Now I move the switch to position 2 in the following circuit, the capacitor is connected to resistive load instead of the voltage source.

## Capacitor working principle: Charging and discharging

The capacitor will now work as a source for the resistor and voltage across the capacitor will start to lose its stored charge by passing current.

By losing the charge, the capacitor voltage will start to decrease. For a constant resistor, the current will also start to reduce as voltage decreases. Similarly, the current will also go to zero after the same time duration.

To find the voltage and current of the capacitor at any instant, use the following capacitor discharging formulas:. Notice the above graph is below the zero line because of the direction of current flow during discharging phase is opposite to that of charging phase. As the resistor and capacitor are connected in seriesso the current is the same for both.

Where voltage across the resistor is different and represented by the following formula:. In all the above discussion, we suppose an uncharged capacitor, however, it may not always be the case. Here we are interested in charging a capacitor which has already some charge stored on it. Because of the charge stored, the capacitor would have some voltage across it i. Now we are connecting the above capacitor to a circuit with source voltage E.Toggle navigation.

Once you delete a sample, it is permanently deleted. If you try to delete a sample a second time, or a sample that does not exist, you will receive a "404 not found" response.

However, if you try to delete a sample that is being used at the moment, then BigML. To list all the samples, you can use the sample base URL. By default, only the 20 most recent samples will be returned.

You can also list all of your correlations. Example: "This is a description of my new correlation" discretization Object Global numeric field transformation parameters. See the discretization table below. None of the fields in the dataset is excluded. Specifies the fields that won't be included in the correlation. That is, no names or preferred statuses are changed. This can be used to change the names of the fields in the correlation with respect to the original names in the dataset or to tell BigML that certain fields should be preferred.

All the fields in the dataset Specifies the fields to be considered to create the correlation. It is to be applied globally with all input fields. A Discretization object is composed of any combination of the following properties.

For example, let's say type is set to "width", size is 7, trim is 0. Field Discretizations is also used to transform numeric input fields to categoricals before further processing. However, it allows the user to specify parameters on a per field basis, taking precedence over the global discretization. It is a map whose keys are field ids and whose values are maps with the same format as discretization.

It also accepts edges, which is a numeric array manually specifying edge boundary locations. If this parameter is present, the corresponding field will be discretized according to those defined bins, and the remaining discretization parameters will be ignored. The maximum value of the field's distribution is automatically set as the last value in the edges array.

A value object of a Field Discretizations object is composed of any combination of the following properties. You can also use curl to customize a new correlation. If you do not specify a range of instances, BigML. If you do not specify any input fields, BigML. Read the Section on Sampling Your Dataset to lean how to sample your dataset. Once a correlation has been successfully created it will have the following properties. The Correlations Object of test has the following properties. If p-value is greater than the accepted significance level, then then it fails to reject the null hypothesis, meaning there is no statistically significant difference between the treatment groups.

It has the following properties: The Chi-Square Object contains the chi-square statistic used to investigate whether distributions of categorical variables differ from one another. This test is used to compare a collection of categorical data with some theoretical expected distribution.

He's the betting expert and founder of Pregame. Tim Donaghy pleaded guilty to two felony charges Wednesday, including providing "picks" on the outcome of games he officiated. There was no admission of "game-fixing" (i.

An examination of the real numbers calls into extreme question whether the whole story is being told. The odds of that happening randomly are 32,768 to 1. In the two years prior (i. Now consider what we must believe in order to conclude that Tim Donaghy did not fix games: first, that a person troubled enough to provide inside information to criminals was able to referee games in which he had a financial interest in the outcome without any bias.

We also must believe that information alone allowed big bettors to beat Las Vegas 15 straight times. And finally we must believe the fact that Donaghy become a much more active referee recently is a coincidence rather than evidence of an effort to increase his influence on games.

Keep in mind that a single call can affect the outcome of a game. Last season alone, 13 games refereed by Tim Donaghy fell within A SINGLE POINT of the Las Vegas point spread. In the last two seasons alone, the winner of 14 NBA games refereed by Tim Donaghy was decided by a single bucket or less. Over 50 BILLION dollars is gambled on the NBA each season. If not a single call was affected by Donaghy's bets, then we have the whole story. Voleyball and american football.

Handball, add tip and stake and save your bet.The first thing you should know, however, is the difference between a "bankroll" and a "buy-in. Your bankroll is the entire amount of money you have available with which to play poker over a period of time. It would be unwise to bring your entire bankroll at any one time or to use all the money you have with you to buy chips right off.

Not only are there ups-and-downs during a single poker session but also ups-and-downs over a period of time. Your bankroll should tide you over the low periods. If not, then you need to think about how poker is affecting your overall finances. One more point about digging into your reserve when your chip stack is low.

In a regular game, it is never advisable to wait until your stack is depleted before buying more chips. If your stack is too low, you can't play with strength. It is better to buy more "ammo" (chips) before your stack gets low or end this particular playing session. It is not so much that you walk away from the poker table with something, it is that you won't play those chips from a position of weakness, which rarely wins.

To be able to walk away in this situation takes discipline, which marks the good players from the bad players. Bankroll-size suggestions range from 200 times the big bet at the level you are playing to 300 times the big bet.

These amounts may seem like large numbers, but the fact is that even consistent winning professional poker players have downswings in their bankroll that may sometimes reach 200 times the big bet of the limits at which they are playing. Any number of factors or a combination of factors may cause these downswings. They include a run of bad cards, poor play for one reason or another, poor game or table selection, or health issues.

It is recommended to start with 300 times the big bet. A lot of players play much better when they have this cushion.

Some have played at levels in which they had less than 100 times the big bet in their bankroll, and it usually hurts their play. This is obviously a purely psychological hurdle, but when reduced to facts, it makes sense.

Keep in mind that 50 times the big bet is a fairly common downswing and nothing to become too concerned about if you are still playing to the best of your ability.

Trying to just break-even when you are down is a thought that should never enter your mind. One last suggestion that is extremely important on your trip to becoming a successful poker player is record keeping.
