Overview

This experiment uses a Triac-based dimmer circuit to control the brightness of a lamp.

Components Required

• Triac
• Resistors
• AC Lamp
• Power supply
• Triggering Circuit
• Breadboard and wires

Procedure

1. Connect the Triac in series with the AC lamp.

2. Use a triggering circuit to adjust the phase angle, controlling the brightness of the lamp.

Expected Result

The brightness of the lamp will vary depending on the phase angle control of the Triac.
