48. In a R-L parallel circuit, total current lags behind the applied voltage."  True  False In a R-C circuit, whether parallel or series, the total current will always be inphase with the applied voltage."  True  False The general equation of Ohm's Law in AC circuit states that the current through an element is equal to the product of the voltage across it and its impedance.  True  False The power drawn by a inductor or capacitor is called apparent power.  True  False

The figure below depicts the winding of an electric motor. It has a resistance of R = 15.3 and an inductance of L = 20.6 mH (watch the multiplier!!!). 110 V 60 Hz. www R Motor Connecting this motor to an alternating source of 110 Volts, and a frequency of 60 Hertz (shown in the figure), your task is finding the current = V/Z Amperes that flows throughout the winding of the motor. Recall that your reference is the incoming voltage V.

9. A noninductive load with a resistance of 30 Q2 is connected in series with a capacitor. The capacitor has a capacitive reactance of 25 Q and negligible resistance. The series circuit is energized from a 210 V, 60 Hz source. Determine: a. the impedance of the series circuit. b. the current, in amperes. c. the loss in volts across the noninductive resistance load. d. the loss in volts across the capacitor.
