1.A small factory utilizes the standard 120V/Hz voltage. When all the heavy machinery is operational, the total electric current flowing into the factory is 1.2 amperes. The phase angle between the voltage and current waveforms is measured to be 2.1 radians. Find the real power dissipated by the factory. Round off your answer to two decimal places. 2. P = Vrms x Irms x pf 3.Vrms = 120, Irms = 1.2?, I converted 2.1 to degrees and got 120.321. I thought it would just be 120 x 1.2 x cos(120.321).
