Overview

This experiment demonstrates a zero-crossing detection circuit to identify when an AC signal crosses zero voltage.

Components Required

• Op-Amp or Comparator
• Resistors
• AC power source
• Power supply
• Breadboard and wires

Procedure

1. Connect an Op-Amp or comparator to the AC signal.

2. Observe the output to detect when the AC signal crosses zero voltage.

Expected Result

The circuit will output a signal indicating when the AC voltage crosses zero, useful for synchronization in AC systems.
