A capacitor bank is wired in series with a light bulb. A switch is used to charge and discharge the circuit. The bulb dims as the circuit goes through the RC time constant.
The demonstration DMM can be used in place of the bulb for more accurate information due to the performance characteristics of the bulb.
This demo can be found in cabinet F on shelf 4 of the UCSD PUL Demo Room (WLH 2015).
