A multimeter can measure which quantities?

• A. Resistance, magnetic field and current
• B. Voltage, current and resistance
• C. Current voltage and magnetic field
• D. Wattage, conductance & capacorange

Answer: (B)

A multimeter is designed to read the three basic electrical quantities: voltage, current, and resistance. You measure voltage by placing the probes across the component or circuit to read the potential difference in volts (AC or DC, depending on the meter). To measure current, you must put the meter in series with the circuit so the same current flows through the meter, yielding amperes (again, DC or AC depending on the meter). To measure resistance, you first ensure the circuit is powered off, then connect the probes to the component so the meter can push a small current and display the resistance in ohms. Magnetic field isn’t a standard readout on a typical multimeter; that requires a gaussmeter or magnetometer. Wattage isn’t directly measured by most meters—the power you’d calculate from voltage times current, though some advanced meters can show a derived power value. Conductance is the reciprocal of resistance and isn’t a common direct display on basic meters. Therefore, the core measurements a standard multimeter provides are voltage, current, and resistance.
