3. An inductor/resistor circuit is powered by a direct current EMF of 3.00 V until the inductor is fully powered. The decay coefficient of the circuit is 2.15 ms. The inductor has a value of 140 mH.

a) After the EMF is turned off, how long does it take the current in the circuit to drop from a max of 46.2 mA to 11.5 mA?

b) What is the value of the resistor?

c) If the inductor has a length of 0.75 cm and 3000 loops, what is its cross sectional area?
