Question

A resistor with R = 30.0 Ω and an inductor with L = 0.600 H
are connected in series to a battery that has emf 50.0 V and negligible
internal resistance. At time t after the circuit is completed, the energy
stored in the inductor is 0.400 J. At this instant, what is the voltage
across the inductor?
