Class 12PhysicsElectric Potential and CapacitanceCharging and Discharging of Capacitance and RC circuit (DC)
MediumThe plates of a capacitor are charged to a potential difference of $V \, \text{volts}$ and then connected across a resistor. The potential difference across the capacitor decreases exponentially with respect to time. After one second, the potential difference between the plates is $V/3$; then after two seconds from the start, the potential difference between the plates is
- A$V/3$
- B$V/6$
- C$V/9$
- D$2V/3$
