A uniformly wound solenoid having an inductance L and resistance R is cut into two identical halves and the two halves are connected parallel The combination is now connected to a battery of negligible internal resistance and with emf E 1 The time constant of resulting circuit is R The rate at which the power supplied by the battery increases is 4E L The rate at which energy is stored by inductor initially is 4E R initially The rate at which energy is drawn from battery after a long time is 4E2 R
