What is a neon tester used for?
Right Answer is:
Testing voltage
SOLUTION
A neon tester is a tool used for testing voltage in electrical circuits.
- Purpose: Neon testers are used to detect the presence of voltage in electrical circuits.
- Working Voltage: They typically operate within a voltage range of 100 to 250 volts AC.
- Construction: Neon testers consist of a glass tube filled with neon gas and electrodes at both ends.
- Safety Feature: A high-value resistor is included in series with one electrode to limit current flow to 300 microamps at the maximum voltage.
- Indicator: The neon gas glows when voltage is present, indicating a live circuit.
