Light bulb with a capacitor

The power source can be a power supply, Genecon generator or battery pack.

Light bulb with a capacitor

Catalog: 
5C30.30
Location: 
Ca4
The Genecon hand cranked generator is used to charge the 1 F capacitor and then discharged through a bulb. It takes a long time indicating a time constant.

Parallel plate capacitor

Here the dielectric is out of the capacitor.

LR time constant on a scope

The stranded core made up of many insulated rods reduces Eddy currents and has t

LR time constant on a scope

Catalog: 
5J20.10A
Location: 
Channel A of the oscilloscope is across the signal generator and channel 5 is across the inductor. The waveform varies with the changing time constant.
