Question:
The displacement current flows in the dielectric of a capacitor during charging
Options:
becomes zero
has assumed a constant value
is increasing with time
is decreasing with time
Correct Answer:
is increasing with time
Explanation:
According to Maxwell's hypothesis, a displacement current will flow through a capacitor when the potential difference across its plates is varying. Thus a varying electric field will exist between the plates and this displacement current is same in magnitude to the current flowing in outer circuit.
