Q: What tool is used to measure electrical voltage?

Voltmeter — A voltmeter is specifically designed to measure voltage (potential difference).

Q: Which setting on a multimeter is used to measure voltage?

Volts — The 'Volts' setting allows the multimeter to measure electrical potential difference.

Q: What is the unit of measurement for voltage?

Volt (V) — Voltage is measured in Volts (V), representing electrical potential difference.

Q: When measuring voltage, a voltmeter should be connected in:

Parallel — Voltmeters are connected in parallel to the circuit component to measure the voltage across it.

Q: What safety precaution should be taken before using a voltmeter?

Ensure the meter is set to the correct voltage range. — Selecting the proper voltage range prevents meter damage and ensures accurate readings.

Q: What does a 'clamp meter' typically measure?

Current without breaking the circuit. — Clamp meters measure current flowing through a conductor without direct contact.

Q: What is the purpose of a voltage tester (non-contact)?

To detect the presence of voltage. — Non-contact voltage testers detect the presence of voltage without physical contact.

Q: Which tool would you use to verify the integrity of a fuse?

Ohmmeter — An ohmmeter is used to check continuity; a fuse with continuity is good.

Q: What is the best way to determine if a wire is live (carrying voltage)?

Use a non-contact voltage tester. — A non-contact voltage tester provides a safe method to detect the presence of voltage.

Q: What does a higher voltage typically indicate?

A greater electrical potential difference — Higher voltage indicates a greater potential difference driving the flow of current.
