6 FAQs about [The moment when the circuit containing the capacitor is closed]

When does a capacitor act as an open circuit?

The capacitor acts as open circuit when it is in its steady state like when the switch is closed or opened for long time.

Does a current flow through a capacitor when it is closed?

No current flows, yet there is still a potential difference at its open terminals so potential between points does not require that a current flows. In the given circuit when the switch is closed, some current will still flow through certain components even when the capacitor has reached its peak voltage and its current is zero.

What happens when a capacitor is closed?

When switch S is closed, the capacitor is connected directly to the power supply. As there is virtually no resistance in the current path, the capacitor charges up almost instantly to the supply voltage. When S is opened, the capacitor is charged up to V 0, the full supply voltage. Resistor R, connected in parallel, experiences the same voltage.

What is the difference between a capacitor and a closed circuit?

Capacitor: at t=0 is like a closed circuit (short circuit) at 't=infinite' is like open circuit (no current through the capacitor) Long Answer: A capacitors charge is given by Vt = V(1 −e(−t/RC)) V t = V (1 − e (− t / R C)) where V is the applied voltage to the circuit, R is the series resistance and C is the parallel capacitance.

What current still flows in a circuit when the switch is closed?

In the given circuit when the switch is closed, some current will still flow through certain components even when the capacitor has reached its peak voltage and its current is zero. What current still flows in the circuit? Close. You've identified the correct (sub)circuit. However, the voltage at the open capacitor terminals will not be zero.

What happens if a capacitor is a short circuit?

(A short circuit) As time continues and the charge accumulates, the capacitors voltage rises and it's current consumption drops until the capacitor voltage and the applied voltage are equal and no current flows into the capacitor (open circuit). This effect may not be immediately recognizable with smaller capacitors.
