Answer Posted / sai
Because the relationship between voltage and current in a capacitor is:
i = C*dv/dt
An instantaneous change in the voltage across a capacitor would require that the rate of change of the voltage (dv/dt) be infinite, and hence the current would have to be infinite.
For inductors, the relationship is:
v = L*di/dt
In order for the rate of change of current to be infinite (instantaneous change), the applied voltage would have to be infinite.
