Question

A time varying voltage is applied across `A` & `B` such that voltage across capacitor is given by `V_(C)=2sin2t`. What is maximum potential difference across the reistance?
A. `9V`
B. `18V`
C. `3V`
D. `6V`

Answer 1

Correct Answer - A
`q=CV` brgt `=[6xx3sin2t]xx10^(-6)`
`i=(dq)/(dt)[6xx3xx2cos2t]xx10^(-6)`
`V_(R)=iR=9cos2timpliesV_("max")=9V`
