PIRA Classification: 5F30.60

Description: A neon lamp is placed in parallel with a capacitor in a series RC circuit. The neon lamp fires at approximately 80 V and will cause the capacitor to charge and discharge at a given rate. If desired, a scope can be used to trace the voltage across the capacitor.

Special Instructions: The resistance is variable so the period of the circuit can be changed.

Condition: Good

Setup time: 2 minutes
