Introduction

This practical investigates a.c. circuits containing resistors (R), capacitors (C) and inductors (L). It builds on your previous experiences from Circuits 2 where you looked at circuits with resistors and capacitors and measured voltages using an oscilloscope. In this practical we are primarily interested in driven LRC circuits. In this experiment, you will investigate the response of circuits containing inductors, resistors and capacitors to different frequencies, and see what happens as the circuit enters resonance. You will investigate damping and oscillations which arise from the interaction between a capacitor and an inductor. By the end of the practical you will see how resonance effects are used to tune radios.
