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...
