Which statement best describes a multimeter's versatility?

• A. It cannot measure resistance
• B. It can only measure voltage
• C. It can measure voltage, current, and resistance.
• D. It is used to insulate circuits

Answer: (C)

A multimeter’s versatility comes from its ability to measure several basic electrical quantities with one tool. It can measure voltage, current, and resistance, which makes it invaluable for diagnosing circuits. Measuring voltage tells you the electrical potential across a component or supply; measuring current shows how much current is flowing through a path (usually by placing the meter in series); measuring resistance reveals how much a component resists current when the circuit is powered off. This combination—voltage, current, and resistance—is what makes the description of a multimeter as capable of measuring all three the best one. The other statements misstate its function: it does measure resistance, it’s not limited to voltage, and it isn’t used to insulate circuits.
