As shown in figure, instantaneous current in branck having capacitor C will be (given `tan^(-1)(4//3)=53^(@))`

A

`20sqrt(2)sin(omegat+3pi//4)`

B

`40sqrt(2)sin(omegat+pi//4)`

C

`60sqrt(2)sin(omegat-pi//4)`

D

none of above

Text Solution

Verified by Experts

The correct Answer is:
A
Voltage across capacitor will lag current by `90^(@)`
`thereforei_(C)=(200sqrt(2))/(10)sin(omegat+(pi)/(4)+(pi)/(2))`
`i=20sqrt(2)sin(omegat+(3pi)/(4))`
