An RL circuit in which L = 9.00 H and R = 5.00 is connected to a 24.0 V battery at t = 0.(adsbygoogle = window.adsbygoogle || []).push({});

(a) What energy is stored in the inductor when the current is 0.500 A?

(b) At what rate is energy being stored in the inductor when I = 1.00 A?

(c) What power is being delivered to the circuit by the battery when I = 0.500 A?

I got the energy; that was pretty straightforward. Just U=1/2 LI^2.

For the rate of energy, I tried solving for energy at 1.00 A, then solving for t when inductor is at 1A. To do that I used I=V/R(1-e^-Rt/L), then I divided energy by the time to find power but that didn't work. Any tips?
