- #100A 100 ``\Omega`` resistance and a capacitor of 100 ``\Omega``
reactance are connected in series across a 220 V
source. When the capacitor is 50% charged, the
peak value of the displacement current is :-
(1) 4.4 A
(2) 11 2 A
(3) 2.2 A
(4) 11 AdigAnsr: 3Ans : (3)

As we are asked amplitude of displacement current.
So, need not worry about charge on capacitor.
