At t = 0, the current through a 63.0 mH inductor is 43.5 mA and is increasing at the rate of 69.0 mA/s.

What is the initial energy stored in the inductor, and how long does it take for the energy to increase by a factor of 3.5 from the initial value?

2. You want to turn on the current through an inductor (inductance = L) in a controlled manner, so you place it in series with a resistor R = 2200 Ω, a switch, and a dc voltage source V0 = 240 V. After closing the switch, you find that the current through the coil builds up to its steady-state value with a time constant τ. You are pleased with the current’s steady-state value, but want τ to be half as...
