Alternating-Current RC and RLC Circuits

PHY 201 & 231

Lab PDF 1
Lab PDF 2

Based on Loyd #37. In this experiment, the students will meausre the voltage across each element in a series RC and a series LCR circuit. This is to show that in an RC circuit, the resistor voltage and the voltage across the capacitor are ninety degrees out of phase. From the measurements, the value of the capacitance of a capacitor in an RC circuits will be determined.

Only two of the four inductance decade box models can be used in this experiment - models 22 and 32. Only one of these two models is needed for each table. If there are not enough Resistance Decade boxes (Central Scientific models), put out the Aerovox Decade Resistors model ARD-23.

The oscilloscope is not used in the Loyd lab setup. For the Loyd set up, put out a 1 micro-fahrrad capacitor.
