An exponentially increasing voltage of 02e2t v is impressed

Question

1. A constant voltage of 12 V is impressed on a series circuit composed of a 10-? resistor and a 10^-4-H inductor. Determine the current after 2 µs if the current is zero at t = 0

2. An exponentially increasing voltage of 0.2e^2t V is impressed on a series circuit containing a 20-? resistor and a 10^-3-H inductor. Calculate the resulting current as a function of time using i = 0 at t = 0.
