In a purely capacitive ac circuit, the value of current is:

Options

A. `i_(m) sin ( omegat + (pi)/(4))`
B. `i_(m) cos (omegat + (pi)/(2))`
C. `i_(m) sin (omega t + (pi)/(2))`
D. `i_(m) cos ( omegat + (pi)/(4))`

Answer

C

Explanation

The value of current in pure capacitive ac circuit is given by `i_(m) sin(omegat + (pi)/(2))` .
