Question 1

Which tool measures electrical current in a live conductor without breaking the circuit?

Accepted Answer

Clamp meter

Answer

A clamp meter's jaws encircle the conductor and detect the magnetic field produced by current flow, allowing measurement without interrupting the circuit.

Question 2

What is the primary function of a multimeter?

Accepted Answer

Measure voltage, current, and resistance in one device

Answer

A multimeter (volt-ohm meter) combines functions to measure AC/DC voltage, current, and resistance in a single portable instrument.

Question 3

What is the purpose of a non-contact voltage tester?

Accepted Answer

Detect the presence of voltage without touching the conductor

Answer

A non-contact voltage tester detects the electromagnetic field surrounding a live AC conductor, signaling voltage presence without physical contact.

Question 4

What does a torque wrench allow a technician to do?

Accepted Answer

Apply a precise amount of rotational force to a fastener

Answer

A torque wrench measures and limits the rotational force applied to a fastener, ensuring tightening meets manufacturer specifications.

Question 5

Which tool is specifically designed to remove insulation from electrical wire without damaging the conductor?

Accepted Answer

Wire stripper

Answer

A wire stripper has calibrated notches sized to each wire gauge that grip and cleanly remove insulation while protecting the conductor underneath.
