Question R13 Q22 - NSB MS 2014

A resistive AC circuit supplied by a voltage of 120 root mean squared dissipates 120 watts of power. A secondary resistive circuit, identical to the first one, dissipates 180 watts of power. What is a possible reason the second circuit dissipates more power than the first one?

W) The power factor for circuit #2 is not equal to 1

X) The voltage source from circuit #2 contains harmonics

Y) The higher power dissipation for circuit #2 occurs only during the transitory period

Z) Parasitic losses are present in circuit #2
