The power in the AC circuit is 880W. The ammeter showed 8A, and the voltmeter 220V. Determine the phase shift between current and voltage.
The power of the AC circuit is found by the formula:
P = I * U * cosa
cosa = P / I * U = 880/8 * 220 = 0.5
a = 60 degrees = pi / 3
8A 220V /. 16A 440V / 24A 660V / 32A 880V
