Experiment En-12

LCR Series Circuit

Description: An inductor, a variable resistor, and a variable capacitor are connected in series with a variable voltage supply. An oscilloscope is connected so that it can read both the voltage drop across the capacitor and the voltage of the power source.


Experimental setup. Capacitor is marked "C," resistor is marked "R, and the inductor is marked"L". The oscilloscope, showing a waveform produced by the circuit, is in the upper left. The box between the circuit main and the oscilloscope houses the transformers.


Schematic for experimental setup.



Materials: wire, oscilloscope, probes, variable capacitors, variable resistor, inductor
