Application +4 | -1
A parallel capacitor made of circular plates of radius 10.0 cm10.0 \mathrm{~cm} has a capacitance of 200 pF200 \mathrm{~pF}. The capacitor is connected to a 200 a.c. supply with an angular frequency of 200 rad s−1200 \mathrm{~rad} \mathrm{~s}^{-1}.
(i) What is the r.m.s. value of conduction current?
(ii) Is the conduction current equal to displacement current?
View answer and explanation
Correct option: A
8μA8 \mu \mathrm{A}; Yes
Option A (8μA8 \mu \mathrm{A}; Yes) is correct because the conduction current is equal to the displacement current in a capacitor, and its value is calculated using the given parameters.
