1A periodic sinusoidal voltage is applied to a nonlinear loa

1)A periodic, sinusoidal voltage is applied to a nonlinear load impedance. The resulting instantaneous current is given in the following. Calculate the P, Q, D , distortion factor and power factor.

v=200sqrt2 sin wt

y 200 2 sin cot V2 20 sin cot -45°)+10sin 20t +609 +10sin 3ot 600

Solution

Real power P= 200*2*cos(0+45)

=400*cos45

=282.54 watts

Therefore P=282.84 watts
