An inductor with L = 150mH and r = 200(Omega) is in series with a capacitor, a resistor, and a generator of w = 1000 rad / s The voltage across the inductor Vind is measured to be 10.87 V, VR is measured to be 4.65 , and Vc is measured to be 5.96 V. What is the generator voltage V? (Hint: This is the measurement to be performed in this laboratory for LCR circuits. Use the appropriate equations to find VL and Vr' and then use them and the values of VR and VC to calculate V.)
