Description

A Continuity Tester with LED Indicator is a simple electronic tool used to check if there is a continuous electrical path (connection) between two points in a circuit. It’s especially useful for troubleshooting wires, connections, switches, and PCBs.

🔧 Basic Description:

  • Purpose: To detect whether two points in an electrical circuit are electrically connected.

  • Indicator: An LED (Light Emitting Diode) that lights up if continuity exists.

  • Power Supply: Typically powered by a small battery (e.g., 3V or 9V).

⚙️ Working Principle:

  • When the test probes are connected across a continuous (unbroken) circuit, current flows through the circuit.

  • This current passes through the LED, causing it to light up, indicating continuity.

  • If the circuit is open (broken), no current flows, and the LED remains off.

🧩 Components Used:

  1. Battery (3V to 9V) – Provides power to the tester.

  2. LED – Acts as the visual indicator.

  3. Current Limiting Resistor – Protects the LED from excess current.

  4. Test Probes or Wires – For connecting to the circuit under test.

✅ Advantages:

  • Easy to use.

  • Instant visual feedback via LED.

  • Portable and inexpensive.

  • No risk of damaging sensitive components since it uses low voltage and current.

⚠️ Limitations:

  • Cannot measure resistance or other parameters.

  • May not work well in circuits with high resistance or low voltage.
