Question:

Options:

a

b

c

d

Correct Answer:

c

Explanation:

for a DC source the conduction current and displacement current (capacitor current) are not the same. Therefore, by Maxwell's equation for a time varying voltage (AC voltage), both conduction and displacement currents are the same. current is AC.  In DC source, the polarity of the voltage is constant.
