: The RL circuit below has a switch (not shown) which was open until t = 0, at which time the switch

was closed (meaning the current in the circuit was zero up until t = 0, and then it started flowing until

t = 0). What is the rate that work is being done by the potential electric field (a) in the battery; (b)

in the resistor; and c in the inductor? Express your answers in terms of E, I, and R.
