Unformatted text preview: Nanyang Technological University School of Physical and Mathematical Sciences Division of Physics and Applied Physics PAP 119 Physics Lab Ib Experiment 8: LRC Circuit Background An LRC circuit is an electrical circuit that consists of a resistor (R), an inductor (L) and a capacitor (C), connected in series or in parallel (see Figure 1). (a) (b) Figure 1: A (a) series LRC circuit and a (b) parallel LRC circuit. In an AC circuit, the impedance, Z , measured in Ω , is a measure of the overall opposition of a circuit to the flow of an electrical current. Because the capacitative and inductive reactances vary with the frequency of the AC current, the impedance of a circuit containing capacitors and inductors also varies with AC frequency. For a circuit with AC current flowing at angular frequency ω , its impedance is given by Z = p ( X L − X C ) 2 + R 2 , (1) where X L = ω L is the inductive reactance, X C = 1 /ω C is the capacitative reactance, R is the resistance, and ω = 2 π f ( f is the linear frequency)....
