Question:

A coil draws 15 A when connected to a 220-V 60-Hz ac line. When it is in series with a 4-Ω resistor and the combination is connected to a 100-V battery, the battery current after a long time is observed to be 10 A.

(a) What is the resistance in the coil?

(b) What is the inductance of the coil?
