consider the rate pl at which energy is being stored in the r-l circuit of (figure 1). answer these questions, in terms of e, r and l as needed.
(a) What is PL at t = 0 just after the circuit is completed?
(b) What is PL at t → [infinity] , a long time after the circuit is completed?
(c) What is PL at the instant when i = e/2R one-half the current's final value?
