Question

A 24-mH inductor, an 8.1-Ω resistor, and a 5.9-V battery are connected in series as in the figure below. The switch is closed at t = 0. A circuit contains a battery, a switch, an inductor, and a resistor. The circuit starts at the positive terminal of the battery labeled emf ℰ, goes through the switch labeled S, goes through the inductor labeled L, goes through the resistor labeled R and ends at the negative terminal of the battery. 

(a) Find the voltage drop across the resistor at t = 0. V 

(b) Find the voltage drop across the resistor after one time constant has passed. V 

(c) Find the voltage drop across the inductor at t = 0. V 

(d) Find the voltage drop across the inductor after one time constant has elapsed. V
