circuit theory

[anujsharma]

can someone answer plzzz........
if v(t)=160sin(wt+10) and i(t)=5sin(wt-20), then reactive power absorbed by the circuit will be???

[nihar.mahi@gmail.com]

Vrms= 160/sqrt(2)
Irms= 5/sqrt(2)

Angle between V & I= 10-(-20)=30 degrees.

So, reactive power= Vrms x Irms x sin 30
= 160/sqrt(2) x 5/sqrt(2) x 1/2
= (160 x5) / 4
= 200 VAR or 0.2 kVAR
