A coil of inductane `0.2` henry is connected to `600` volt battery. At what rate, will the current in the coil graw when circuit is completed ?

Explanation

As the battery and inductor are in parallel, at any instant, emf of the battery and self emf in the inductor are equal
`|e| = L(dI)/(dt)` or `(dI)/(dt) = (|e|)/(L) = (600V)/(0.2H) = 3000 A s^(-1)`
