Question 1

What is the function of a wire stripper?

Accepted Answer

Removing insulation from electrical wire without damaging the conductor

Answer

A wire stripper removes the plastic insulation from electrical wire while leaving the metal conductor undamaged. It has calibrated notches or adjustable blades matched to common wire gauges to cut only through the insulation.

Question 2

What is a pneumatic nail gun used for?

Question 3

What is a multimeter used to measure?

Accepted Answer

Voltage, current, and resistance

Answer

A multimeter is a versatile electronic measuring instrument that can measure voltage (volts), current (amperes), and resistance (ohms). Many multimeters also measure continuity, capacitance, frequency, and temperature.

Question 4

What is the purpose of a C-clamp?

Accepted Answer

Holding workpieces firmly together or to a surface

Answer
