A coil with an inductance of 2.5 H and a resistance of 14 O issuddenly connected to an ideal battery with e = 79 V. At 0.11 safter the connection is made, what is the rate at which (a) energyis being stored in the magnetic field, (b) thermal energy isappearing in the resistance, and (c) energy is being delivered bythe battery?

and resistance 
is connected to a battery of EMF 12V. Find the energy stored in the magnetic field associated with the coil at an instant 10 ms after the circuit is switched on.
