Consider a simple RL circuit consisting of an ideal battery with voltage 30 V , a resistor of resistance 15 Ω, an inductor of inductance 7.0 H, and a switch all in series. The switch is initially open. a) Determine the ratio of the voltage across the resistor to the voltage across the inductor when the current has a value of 1.5 A. b) How much time has elapsed if the voltage across the resistor is 20 V ?
