1)As a way of determining the inductance of acoil used in a research project, a student firstconnects the coil to a 7.73 V battery and measures a current of 0.94 A. The student thenconnects the coil to a 32.3 V(rms), 88.5 Hzgenerator and measures an rms current of0.423 A. What is the inductance? Answer in units of H. 2)A circuit consists of a 39 Ω resistor and a690 mH inductor connected in series to a 11 Vbattery.What is the value of the current when thecurrent is increasing at the rate of 8 A/s? Answer in units of A.

1)As a way of determining the inductance of a
coil used in a research project, a student first
connects the coil to a 7.73 V battery and measures a current of 0.94 A. The student then
connects the coil to a 32.3 V(rms), 88.5 Hz
generator and measures an rms current of
0.423 A. What is the inductance?
Answer in units of H.
2)A circuit consists of a 39 Ω resistor and a
690 mH inductor connected in series to a 11 V
battery.
What is the value of the current when the
current is increasing at the rate of 8 A/s?
Answer in units of A.
