Consider the RL circuit in Fig. When the switch is closed in position 1 and opens in position 2, electrical work must be performed on the inductor and on the resistor. The energy stored in the inductor is for the resistor energy appears as heat. a. What is the ratio of PL/PR of the rate at which energy is stored in the inductor to the rate at which energy is dissipated in the resistor? b. Express the ratio PL/PR as a function of time. c. If the time constant of circuit is t, what is the time at which PL=PR?
