Capacitors in DC Circuits

When a switch turns on or off the power to an electric circuit, it introduces a change of voltage to the circuit. During turning the power on in a DC circuit containing a capacitor, first, the capacitor is charged. Similarly, at power off, first, a capacitor in the circuit releases its charge to the circuit. Consequently, a delay is associated

22.2: AC Circuits

For a circuit with a capacitor, the instantaneous value of V/I is not constant. However, the value of V max /I max is useful, and is called the capacitive reactance (X C) of the component. Because it is still a voltage divided by a current (like resistance ), its unit is the ohm. The value of X C (C standing for capacitor) depends on its capacitance (C) and the frequency

6 FAQs about [Circuit containing capacitors]

What is a capacitor in a RC circuit?

The capacitor is an electrical component that stores electric charge. Figure 1 shows a simple RC circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.

Why is a capacitor a fundamental element?

What does a capacitor do in a DC Circuit?

A capacitor has a storage capability for electricity. When it is part of a DC circuit, it exhibits an apparent opposition to a change in the circuit voltage. When a switch turns on or off the power to an electric circuit, it introduces a change of voltage to the circuit.

Can a capacitor be added to an electric circuit?

Adding a capacitor to an electric circuit is equivalent to adding a closed tank with limited capacity or a tall tank (with walls that are tall enough and comparable with the main reservoir) at the end of a pipeline.

What happens when a capacitor is inserted in a DC Circuit?

When a capacitor is inserted inside a DC circuit, for a short period of time after the switch is turned on, current flows in the circuit. In the beginning, this current is higher but gradually becomes smaller and smaller until it diminishes. This is when the capacitor has charged, and it does not accept an electric charge anymore.

What if a circuit has a capacitor other than resistors and sources?

This action is not available. Introducing when a circuit has capacitors and inductors other than resistors and sources, the impedance concept will be applied. Let's consider a circuit having something other than resistors and sources. Because of KVL, we know that: vin = vR +vout v i n = v R + v o u t The current through the capacitor is given by:
