Charging and Discharging of Capacitor with Examples

When a wire is connected across a charged capacitor, as has been illustrated in fig. 6,49, the capacitor discharges. For doing so, a very low resistance path (i.e., wire) is connected to a switch parallel to the capacitor, as can be seen in fig. (b). When the switch is closed, as shown in fig.(b), then electrons existing on plate B start moving towards plate A via

Capacitor Discharging

Below is a typical circuit for discharging a capacitor. To discharge a capacitor, the power source, which was charging the capacitor, is removed from the circuit, so that only a capacitor and resistor can connected together in series. The capacitor drains its voltage and current through the resistor. Variables in Capacitor Discharge Equation

6 FAQs about [Under what circuit does the capacitor discharge]

How does a capacitor discharge?

Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination by closing the switch.

What is discharging a capacitor?

Discharging a Capacitor Definition: Discharging a capacitor is defined as releasing the stored electrical charge within the capacitor. Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging.

Can a capacitor be discharged through a resistor?

In an experiment to study the discharge of a capacitor through a resistor, it was observed that the voltage across the capacitor decreased to half of its initial value in 2 minutes. If the initial voltage was 12 V and the capacitance of the capacitor is 1500 μF, calculate the resistance of the resistor.

What is a capacitor discharge graph?

Capacitor Discharge Graph: The capacitor discharge graph shows the exponential decay of voltage and current over time, eventually reaching zero. What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges.

What happens when a capacitor is connected to a DC source?

Charging and Discharging of Capacitor with Examples- When a capacitor is connected to a DC source, it gets charged. As has been illustrated in figure 6.47. In figure (a), an uncharged capacitor has been illustrated, because the same number of free electrons exists on plates A and B.

How do I know if a capacitor is fully discharged?

Ensure a secure connection. Wait: Allow the capacitor to discharge completely. This may take a few seconds to a minute, depending on the capacitance of the capacitor. Double-Check: Use a multimeter to verify that the voltage across the capacitor terminals has dropped to near-zero. This confirms that the capacitor is fully discharged.
