Homework Statement
A coil of inductance 0.5 H is connected to a 18V battery. Calculate the rate of growth of current?
Homework Equations
E=-L(dI/dt)
The Attempt at a Solution
Actually I have the solution but the problem is that in the book they have assumed that the back emf that would develop due to increasing current would be the same as emf of the battery? i.e its written as dI/dt=E/L=18/0.5= 36 A/s
How is it possible? Or am I thinking wrong
