7. A 500 resistor and a real inductor with a pure inductance of L and an internal resistance of r are in series with a generator with a voltage of V = 10.0 V and an angular frequency of = 1000 rad/s. The voltage across the real inductor is measured to be 4.73 V, and the voltage across the 500 resistor is measured to be 6.57 V. What is the value of L and r? (Hint—This is the measurement to be performed in this laboratory exercise. Use the appropriate equation to find , then the appropriate equations to find VL and Vr, and then the appropriate equations to find L and r. Finally, find L from the known value of .) Show your work.

Explanation / Answer
1)
The current in the resistor and the voltage across the resistor are in phase, the current is in phase with the voltage
2)
In the case of the inductor current of the inductor lags 90° behind to the voltage across inductor. option b. the voltage leads the current by 90°
3)
A generator can act as a capacitor and inductor or resistance, depending on the case there are different phase angles, option d
4)
vrms=vmax/2
vrms=5/2
vrms=3.535V
