Charging a Capacitor. When a battery is connected to a series resistor and capacitor, the initial current is high as the battery transports charge from one plate of the capacitor to the other.The charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage.
Q i is the initial charge stored on capacitor terminals which causes the initial voltage on its terminals v i.. Now we are connecting the above capacitor to a circuit with source voltage E. There will be a difference between the source voltage and capacitor voltage, so the capacitor will start to charge and draw current according to the difference in voltage.
The current flowing in this circuit can be calculated using the definition of current, and the charge on the capacitor. Current is the rate of charge passing past a point, which is the same in this case as minus the rate of charge left on the capacitor - the capacitor losing charge corresponds to a positive current flowing from its positive plate to its negative plate.
Step 3) To begin charging the capacitor you need either a test light or a resistor. Often times these are included with the purchase of a capacitor but can be purchased separately if necessary. A) Using a Test Light: A test light is the simplest way to charge a capacitor. All you need to do is take the power and ground of the test light and ...

At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero; As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge decreases is proportional to the amount of current, p.d or charge it has left

When a capacitor is charging, the way the charge Q and potential difference V increases stills shows exponential decay. Over time, they continue to increase but at a slower rate; This means the equation for Q for a charging capacitor is:; Where: Q = charge on the capacitor plates (C); Q 0 = maximum charge stored on capacitor when fully charged (C); e = …
By applying a voltage to a capacitor and measuring the charge on the plates, the ratio of the charge Q to the voltage V will give the capacitance value of the capacitor and is therefore given as: C = Q/V this equation can also be re-arranged to give the familiar formula for the quantity of charge on the plates as: Q = C x V
Further, the charge time of a capacitor is also mathematically defined by the time constant (τ), a concept that combines resistance and capacitance of the circuit into one metric. The time constant is a measure of how long it takes for the voltage across the capacitor to reach approximately 63.2% of its maximum value in a charging or discharging cycle, underlining the influence of …

To move an infinitesimal charge dq from the negative plate to the positive plate (from a lower to a higher potential), the amount of work dW that must be done on dq is (dW = W, dq = frac{q}{C} dq).
