Capacitors - Technical MCQs

Q1:

When a circuit consists of a capacitor and a resistor in series with a voltage source, and the voltage across the resistor is zero, then the capacitor is:

A charging

B discharging

C fully charged

D fully discharged

ANS:C - fully charged

Uncharged capacitor acts as a short to current initially and after fully charged it acts as an open in the circuit.

So no voltage is zero across the series connected resistor because there is no current.
