Consider an R-L circuit with a DC voltage source, as shown in the figure. This circuit has a current 1, when t <0. At t=0 the switch is thrown removing the DC voltage source from the circuit. The current decays to I(t) at time t AA VVV R A.) What is the power, Pr(t), flowing into the resistor, R, at time t? Express your answer in terms of I(t) and R. B.) What is the power flowing into the inductor? Express your answer as a function of R and I(t).
