This Demonstration shows how different circuit parameters can affect the blinking frequency of a bulb in an RC circuit with a specified breakdown voltage. When the potential across the capacitor is less than the breakdown voltage of the bulb, its potential increases according to the relation . When , the bulb lights up and the potential across the capacitor decreases to zero. This process repeats, causing the light to flash at a constant frequency.
