Q13 of 30 Page 201

You are given a 2μF parallel plate capacitor. How would you establish an instantaneous displacement current of 1mA in the space between its plates?

Displacement current is given by



Capacitance C is given by



Current of the capacitor is given by



C is the capacitance


V is voltage




If we maintained the voltage as V=500v/s, then we can establish an instantaneous displacement current of 1mA in the space between its plates.
