Question:

For the following voltage and current phasors, calculate the complex power, apparent power, real power, and reactive power. Specify whether the pf is leading or lagging.
(a) V = 220∠30° V rms, I = 0.5∠60° A rms
(b) V = 250 ∠ - 10° V rms,
I = 6.2 ∠ - 25° A rms
(c) V = 80∠0° V rms, I = 2.4∠−15° A rms
(d) V = 160∠45° V rms, I = 8.5∠90° A rms
