As a way of determining the inductance of a coil used in aresearch project, a student first connects the coil to a 12.0 - Vbattery and measures a current of 0.630 A. The student thenconnects the coil to a 24.0 - V (rms), 60.0 - Hz generator andmeasures an rms current of 0.570 A. What is the inductance?

Question

As a way of determining the inductance of a coil used in a
research project, a student first connects the coil to a 12.0 - V
battery and measures a current of 0.630 A. The student then
connects the coil to a 24.0 - V (rms), 60.0 - Hz generator and
measures an rms current of 0.570 A. What is the inductance?
