Photo Shows the Demonstration Used by the University of Texas at Austin.

• Included is a simple RC circuit, with a light bulb, 1 farad capacitor & a 6 volt battery.

• The light bulb acts as both a resistor and a current indicator.

• The bulb will glow brightly only at the start of the charging or discharging curve.

• Note: A multimeter is included with the demonstration to view the actual voltage across the capacitor. (See second photo.)

• Suggestion: Use a goose neck video camera for better viewing.

• This is a good introductory demo to accomapny our RC Constant on a Scope demonstration.
