Question
When a capacitor is fully charged in a DC circuit, the
current through it is:Solution
In a DC circuit, once a capacitor is fully charged, no more current flows through it. The voltage across the capacitor equals the source voltage, and the capacitor behaves like an open circuit. Only during charging or discharging does current exist. Thus, after full charging, the current is zero.
