E23: RC Circuit

 

Purpose: To show the charging and discharging of a capacitor in an RC circuit.
Description:

 

DC power supply, 2 7.5-mF capacitors connected in parallel, voltmeter, ammeter, SPDT switch, light bulbs of 40- to 150-W power rating.

Connect the circuit as shown in the diagram in the setup notes. Move the switch to charge and discharge the capacitor, noting the variation in current, voltage, and lighting of the bulb. Vary the resistance by using bulbs of different power ratings.

Equipment List: Storage Location: Hahn N 130A
