A coil of inductance 0.2 henry is connected to 600 volt battery. At what rate, will the current in the coil grow 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)=(600 V)/(0.2H)=3000 As^(-1)`
