An lr circuit contains an ideal 60-v battery, a 51-h inductor having no resistance, a 21-ω 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 = 0 s, the switch is suddenly closed. when the voltage across the resistor is equal to the voltage across the inductor, what is the current in the circuit?
