The voltage across the terminals of a circuit is v(t) = [30 + 20 cos (60? t + 45°) + 10 cos (120? t - 45°)] V If the current entering the terminal at higher potential is i(t) = 6 + 4 cos (60? t + 10°) - 2 cos (120? t - 60°) A
find:
(a) the rms value of the voltage,
(b) the rms value of the current,
(c) the average power absorbed by the circuit.
