Question

An input signal of 5 sin ( 2 pi 1592 t + 0 degrees) is applied to a series RL circuit with resistor R = 1000 ohm and inductor L = 0.1 H. The voltage drop across the resistor is _______.

In a typical AC circuit, the supply voltage is 10 VPK  and frequency is 60 Hz. If the current through the system is 2 APK with a phase angle of 45o, then the power factor is _______.

10 Vpk angle 90 degrees 5 Vpk angle 45 degrees 3.54 Vpk angle 45 degrees 3.54 Vpk angle -45 degrees No correct answer listed 10 mApK angle 90 degrees 5 mApK angle 45 degrees 7.07 mApK angle 45 degrees 7.07 mApK angle -45 degrees No correct answer listed 0.5 0.866 1.73 0.707
