Question

A Parallel platecapacitor made of circular plates each of radius $R=6.0cm$ has a capacitance 100$pF$ is connected to 230$V$ of $AC$ supply of 300 rad/sec.frequency. The rms value of displacement current

• A. $6.9\mu A$
• B. $2.3\mu A$
• C. $9.2\mu A$
• D. $4.6\mu A$

Answer 1

The correct option is A $6.9\mu A$

Given$:-$

$R=6.0cm$

$C=100pF$

$=100\times {10}^{-12}F$

$w=300rad/s$

$I_{rms}=230\times 300\times 100\times {10}^{-12}$

$=6.9\times {10}^{-9}$

$=6.9\mu A$

Hence,

option $\left(A\right)$ is correct answer.
