In addition to voltage, current, and resistance, some advanced digital multimeters can measure which quantities?

• A. Capacitance and Inductance
• B. Temperature
• C. Pressure
• D. Speed

Answer: (A)

Capacitance and inductance are the additional quantities you can measure with some advanced digital multimeters. These meters extend beyond basic DC tests by handling reactive components. To determine capacitance, the meter analyzes how a component stores charge when a signal is applied, often using a small AC test to derive the value. For inductance, it examines how the component impedes changes in current due to magnetic fields, typically by measuring impedance and phase relative to an applied signal. That combination is why meters with LCR capability specifically measure capacitance and inductance. Temperature, pressure, and speed aren’t standard measurements on most DMMs unless a separate sensor is connected, so they aren’t the typical extra quantities these devices measure.
