Question:

A parallel plate capacitor made to circular plates each of radius R = 6cm has capacitance C = 100pF. The capacitance is connected to a 230V A.C. supply with an angular frequency of 300 rad/s. The r.m.s. value of conduction current will be:

Options:

$6.9\mu A$        

$9.6\mu A$ 

$6.3\mu A$ 

$5.7\mu A$ 

Correct Answer:

$6.9\mu A$        

Explanation:

$I_d = I_c = 6.5\mu A$
