An LR ciruit contains an ideal 60-V battery, a 51-H inductor having no resistance, a 21ohm resistor,and a switch S, all in series. Initially, the switch is open and has been open for a very long time.At time t =0s, the switch is suddenly closed. When the voltage across the resistor is equal to the voltage across the inductor,calculate the current in the circuit.
