In a 120 V 10 A ac circuit, if the phase angle between the current and the voltage is 15 degrees 14', what is the reactive power?

S = V x I

S = sqrt(Q^2+P^2)

Where S is the apparent power, Q is the reactive power, and P is the real power. If you think of this in terms of a triangle, Q = V*I*sin(theta), where theta is the angle between voltage and current.
