A multimeter measures

A multimeter measures

• A. Ohms, amps, and volts
• B. Only resistance
• C. Only current
• D. Only voltage

Answer: (A)

Multimeters are versatile instruments designed to measure multiple electrical properties. A standard digital multimeter can measure resistance (ohms), current (amps), and voltage (volts). Resistance is read by applying a small signal and observing the voltage drop across a component; current requires wiring the meter in series in the circuit and using the appropriate current input (with a fuse); voltage is measured by placing the probes across a component or power source. Because it provides readings for all three quantities, it’s best to say it measures ohms, amps, and volts. Some meters add extra tests like capacitance or frequency, but those three are the typical core measurements.
