Electrotechnology 1200 Experiment 10 Series RLC Circuits

BASIC INFORMATIONThe analysis of series RLC circuits is the same as series RC and RL circuits, except themagnitudes of X C and X L must be taken into account. If X C > X L , then the circuit iscapacitive (leading phase angle). If X L > X C , then the circuit is inductive (lagging phaseangle). If X L = X C , then the circuit is resistive (no phase angle). This is a special case, andthe frequency that it occurs at is called resonant frequency.The phasor diagram, impedance triangle and power triangle for a series RLC circuit, whichis capacitive (I leads V S by θ), looks like this:This Experiment attempts to prove the affect frequency has on these relationships in aseries RLC circuit.ELTK1200 Experiment 10 Rev 5 111
