Question 1

A capacitor discharges through a resistor. At time t=0t = 0t=0 the potential difference V V\,V across the capacitor is V0V_0V0​. At time t=3.0 st = 3.0\text{ s}t=3.0 s, V=0.80V0V = 0.80 V_0V=0.80V0​. Which statement is not correct?

At t=6.0 st = 6.0\text{ s}t=6.0 s, V=0.64V0V = 0.64 V_0V=0.64V0​.

The capacitor is fully discharged after t=15 st = 15\text{ s}t=15 s.

The potential difference across the resistor is the same as that across the capacitor at any instant.

The charge on the capacitor decreases exponentially with time ttt.
