A solenoid has a radius of 2.5 cm, 130 turns, and a length of 85 cm. (Inductance for a solenoid is equal to μ0(N2/L)(area)) 1. Suppose the two terminals of the coil are shorted (connected) and it is given some initial current. If after 0.55 ms the current has dropped to 1/30th its value what is the total resistance in the circuit? 2. The current through the solenoid varies as: I(t) = 4t2 - 3t - 12 (in SI units). at t = 3s, what are the energy stored in the solenoid and the voltage across the solenoid?
