In the circuit shown below vg 44cos106t in Volts and Ro 51

In the circuit shown below, vg = 44cos106t (in Volts), and Ro = 51 ?. What is the reactive power (in VARs) supplied by the source? You should calculate the complex power as (1/2)*V*conjugate(I). The reactive power is then the imaginary part of the complex power. Be careful to note that the question asks for the reactive power supplied. Express your answer to two decimal places.

Solution

average power = V² / 2R

= 41
