Consider the circuit below, which is powered by a 6-v battery. switch s is opened at t = 0 after having been closed for a long time. (a) how much energy is stored in the inductor at t = 0? 37.5 correct: your answer is correct. mj (b) what is the instantaneous rate of change of the inductor's energy at t = 0? 7.5 incorrect: your answer is incorrect. w (c) what is the average rate of change of the inductor's energy between t = 0.0 and t = 1.0 s? -.0375 correct: your answer is correct. w (d) how long does it take for the current in the inductor to reach 0.00020 times its initial value?
