Good Luck True/False (Each 2 Points) 1) The cosine curve leads the sine curve by 180 2) The duration of an alternating cycle is called a period. 3) The Si unit of frequency is called a herta. 4) The peak value of a waveform is the maximum instantaneous value as measured from the zero- volt level. 5) The voltage across an inductor leads the current through it by 90 6) The more reactive the load, the lower the power factor. 7) The complex conjugate is found by changing the sign of the real part in the rectangular form. 8) Phasor algebra for sinusoidal quantities is applicable only for waveforms which have different frequencies. 9) The angle associated with the total impedance is the angle by which the applied voltage leads the source current. 10) Impedance is the combingtion of capacitive reactance, inductive reactance, and Multiple Choice Question (Each 3 Points) 1) What is the total impedance ZTof a series network consisting of a s having 10 ? reactance, and a capacitor with is ? reactance?
