Which of the following measurements are made using a multimeter?

A standard multimeter gets its name from combining multiple metering functions into a single device. At its core, it is designed to measure three fundamental electrical properties: voltage (volts), current (amperes), and resistance (ohms). While highly versatile for troubleshooting basic circuits, checking battery voltages, or testing continuity, standard multimeters cannot measure complex radio frequency properties. Signal strength and noise require an S-meter or spectrum analyzer, while impedance and reactance are complex AC properties that must be measured using a specialized antenna analyzer or an LCR meter. Because multimeters are strictly limited to basic electrical parameters, the distractor options covering RF signals and complex impedance are incorrect.
