2. Concepts of RMS value and complex power under harmonic conditions: In the circuit below, the voltage has harmonics. The load is a passive element Z(s) = R + Ls, where R = 0.1 Ohm, and L = 1 mH. t ~ Ult) Figure 2: Problem 2: A circuit with harmonics. v(t) = 10 cos(wt) + 2 cos s (2wt + 7) + cos (3wt − 7) v. (1) • What is the current's time-domain expression i(t)? • What are the RMS values of the voltage and the current? • What are the real power, reactive power, apparent power, and power factor by the load? Hint: If you use phasor/impedance analysis, please make sure you are studying one harmonic frequency at a ime.
