Q. A 100 Ω resistance and a capacitor of 100 Ω reactance are connected in series across a 220 V source. When the capacitor is 50% charged, the peak value of the displacement current is
A) 2.2 A
B) 11 A
C) 4.4 A
D) $11\sqrt{2}$ A
Explanation
[Solution] $Z = 100\sqrt{2}$ Ω; $I_0 = \frac{220\sqrt{2}}{100\sqrt{2}} = 2.2$ A, which equals the peak displacement current. Answer (1).
