Question

An inductor is connected to the terminals of a battery that has an emf of 16.0 V and negligible internal resistance. The current is 4.86 mA at 0.940 ms after the connection is completed. After a long time, the current is 6.45 mA. What are (a) the resistance R of the inductor and (b) the inductance L of the inductor?

Answer:(a) The resistance R of the inductor is

2480.62 Ω(b) The inductance L of the inductor is

1.67 HExplanation:Given;

emf of the battery, V = 16.0 V

current at 0.940 ms = 4.86 mA

after a long time, the current becomes 6.45 mA = maximum current

Part (a) The resistance R of the inductor

Part (b) the inductance L of the inductor

where;

L is the inductance

R is the resistance of the inductor

t is time

Therefore, the inductance is

1.67 H
