With the switch in position S 2, the 10Ω resistor is effectively shorted and therefore disconnected from the 10 volt supply voltage (V).As a result, zero current flows through the resistor, so I R = 0. However, when the switch is moved to position S 1 at time t = 0, a step voltage of 10 volts is applied directly across the 10Ω resistor resulting in a current of 1 ampere (I = V/R) flowing

The Fundamentals of Capacitors in AC Circuits

When the voltage reaches its maximum value, the current will be zero, but as the voltage decreases, the current changes direction. As the current is already at maximum positive flow when the voltage sine wave crosses zero, going positive, it seems that the current comes first, before the voltage, so in a capacitive circuit, the current leads
