Question:
The battery terminal voltage in the figure below is=7.30V and the currentIreaches half its maximum value of5.00Aatt=0.190safter the switch is closed.
A circuit contains a battery, a switch, an inductor, and a resistor. The circuit starts at the positive terminal of the battery labeled emf, goes through the switch labeled S, goes through the inductor labeledL, goes through the resistor labeledRand ends at the negative terminal of the battery.
(a)Calculate the time constant (in s).
(b)What is the potential difference (in V) across the inductor at t = 0.190 s?
(c)What is the potential difference (in V) across the inductor in the instant after the switch is closed at t = 0?
