Circuit with an unknown inductance

0 pts ended
A circuit contains a known resistance of 2.4 kO, and an unknown inductance.

a) When a 12-V battery is connected, what is the current in the circuit a long time after the switch is closed?

b) If it takes 3.1 ms for the current to reach 95% of this value, what is the inductance in the circuit?

c) At the time given in part b, what is the amount of energy that has been stored in the magnetic field of the inductor?
