Question

In the circuit shown, a time varying voltage `V = 2000t` volt is applied where `t` is in second. At time `t 5 ms`, determine the Current through the resistor `R= 4 Omega` and through the capacitor `C 300muF`

Answer 1

Correct Answer - A
At `t=5ms, V=10V`
`:. i_R=V/R=10/4=2.5`
Further, `q=CV=(30xx10^-6)(2000t)=0.6t`
`i_C=(dq)/(dt)=0.6A=` constant
