A resistor and a capacitor are connected in series across an ideal battery having a constant voltage across its terminals as shown.
A resistor and a capacitor are connected in series across an ideal battery having a constant voltage across its terminals as shown. The capacitor initially uncharged. At the moment the switch is closed the voltage across the capacitor is equal to the battery's terminal voltage less than the battery's terminal voltage, but greater than zero. equal to the battery's terminal voltage zero.
