Saad Ghazipura PHY 134 Section 2 LR(C) Circuits Lab Abstract In this lab, the behavior of series LR circuits and LRC circuits will be observed. An LRC circuit is an electrical circuit that contains a resistor (R), inductor (L), and a capacitor. It can either be oriented in series or parallel. This forms a harmonic oscillator. The equations defining the circuit are as such: . The purpose of the 1 Ω resistor is to prevent the variable resistor from the oscilloscope to affect the readings on the oscilloscope. Main Analysis see attached sheets Data: R=100     Voltage(mV) ±.05  mV Time (us) ±2

In the RLC circuit, a resonant frequency was observed for the RLC circuit. For the RC circuit, the battery was charging giving a negative slope for the graph. Sources of error include uncertainty in reading the oscilloscope and the ruler....
