hi guys could any body send me in the right direction with this question because im completely baffled " A 2H coil of negligible resistance while connected to a power supply carries 5A. If it is disconnected from its power supply and connected to a 120 Ω discharge resistor calculate the time taken for the current to fall to 0.25A."
