What set of quantities is commonly measurable with a digital multimeter?

• A. Current, voltage, and resistance
• B. Capacitance only
• C. Inductance only
• D. Temperature and humidity

Answer: (A)

Digital multimeters are designed to read three basic electrical properties that you encounter most in circuits: current, voltage, and resistance. Voltage measures the potential difference across two points, and the meter connects in parallel so it doesn’t load the circuit thanks to its high input impedance. Current measures how much charge is flowing, so you place the meter in series and use a built‑in shunt resistor to convert that current into a readable voltage. Resistance isn’t measured in a powered circuit; you apply a small current from the meter and measure the resulting voltage to compute how much the device resists current, using Ohm’s law.

While some meters offer extra functions, like capacitance or temperature readings, those are not part of the standard, commonly supported trio on most digital meters. Capacitance and inductance measurements are more specialized, and temperature/humidity readings aren’t intrinsic electrical properties like voltage, current, and resistance.

So, the best answer is that a digital multimeter typically measures current, voltage, and resistance.
