A serie RLC Circuit consists of 20ohm Resistor, an inductor with an inductance of 130mH and a variable capacitor. The capacitor is set to give resonance to the circuit at the third harmonic. The instantaneous value of the sinusoidal voltage across the circuit is represented by v(t) = 78 + 120sin251t + 84sin(753t+ pi/5) + 72sin(1255t + pi/4) volts 1.Calculate the iductive reactance at the fundemanetal and 3rd harmonic. 2.Deteremine an expression for the current drawn from the supply 3.Calculate overall power factor of the circuit. Now I dont get how they can ask to get the 3rd harmonic. DO I take 120sin251t as the Third harmonic? which one do I use? So far Ive gathered that the Fundamental Harmonic would be 120Sin251t and to get its inductive Reactance I would multiply the 251*(0.000130) to het the Reactance of the Inductor for the FIRST Harmonic. What baffles me is that theres a CAPACITOR involved? How would that work?
