6 FAQs about [Capacitor charging and discharging parameters]

How do you discharge a capacitor?

Discharging a capacitor: Consider the circuit shown in Figure 6.21. When switch S is closed, the capacitor C immediately charges to a maximum value given by Q = CV. As switch S is opened, the capacitor starts to discharge through the resistor R and the ammeter.

What is capacitor charge?

capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear.At the start, the current will be at its highest but will graduall decrease to zero. The following graphs summarise capacitor charge. The potential diffe

What happens when a capacitor discharges?

As more charge is stored on the capacitor, so the gradient (and therefore the current) drops, until the capacitor is fully charged and the gradient is zero. As the capacitor discharges (Figure 3 (b)), the amount of charge is initially at a maximum, as is the gradient (or current). The amount of charge then drops, as does the gradient of the graph.

What factors affect the rate of charge on a capacitor?

The other factor which affects the rate of charge is the capacitance of the capacitor. A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%).

Why do capacitor charge graphs look the same?

Because the current changes throughout charging, the rate of flow of charge will not be linear. At the start, the current will be at its highest but will gradually decrease to zero. The following graphs summarise capacitor charge. The potential difference and charge graphs look the same because they are proportional.

How does capacitor charge change during charging?
