Question
The impedance of an inductor is (where w=angular frequency in radians per second, j = -1. and L = inductance in Henries). A circuit consisting only of linear resistors, capacitors, and inductors is excited by a sinusoidal voltage source at frequency 10 rad/s and is allowed to reach steady-state. The voltage across any component will be If a complex number is written in exponential form as Ze j theta, the rectangular form will be. In a power system, the power factor (PF) is given by cos(theta v- theta .)- If the PF=1, this means. Given a sinusoidal voltage v(t)=2cos(2 pi 60t) volts that supplies current i(t)=0.001cos(2 pi 60t+33 dgree) amps to some RLC circuit, it can be said that. . The total instantaneous power delivered to the load in a balanced three-phase circuit. A balanced, Y-connected three-phase source is connected to a balanced, Y-connected three- phase load. Which of the following is NOT true: The voltage difference between the source source and load neutral terminals is zero. The total power dissipated by the load is the sum of the power dissipated by each phase. The line-to-line voltage is equal in magnitude to the phase voltage. The line-to-line voltage is displaced 30 degree in phase relative to the phase voltages.Explanation / Answer
