1.

A sinusoidal voltage `V (t) = 100 sin (500 t)` is applied across a pure inductance of `L = 0.02 H`. The current through the coil is :A. `10 cos (500 t)`B. `- 10 cos (500 t)`C. `10 sin (500 t)`D. `- 10 sin (500 t)`

Answer» Correct Answer - 2
`i = i_(0) sin (omega t - (pi)/(2)), i_(0) = (V_(0))/(X_(L))`
