Capacitor with Light Bulbs

Demo

A capacitor, a light bulb, and a battery

Concept Overview:

1. Storage of electric charge

2. Capacitance

Lecturer Procedure

Step(s) to Follow Expected Result

1. Connect capacitor, via corresponding terminals, to battery.

2. Wait 1-3 seconds.

3. Disconnect capacitor from battery; connect to light bulb

Light bulb will turn on quite brightly, but will dim gradually until it stops charging

Variation: Additional set-ups with capacitors of differing capacitance can be added to show the difference in discharge.
