What does the DMM function measure when set to capacitance?

• A. Voltage
• B. Capacitance
• C. Resistance
• D. Frequency

Answer: (B)

When a Digital Multimeter (DMM) is set to measure capacitance, it is specifically designed to assess the ability of a capacitor to store electrical energy in an electric field, which is defined as capacitance. Capacitance is expressed in farads and reflects how much charge a capacitor can hold per unit of voltage. In this mode, the DMM sends a small alternating current through the capacitor and measures how much charge it can store. The results indicate the capacitance value, allowing the user to evaluate the functionality of capacitors in various electronic circuits. This function is particularly useful for troubleshooting issues related to capacitors, understanding circuit behavior, and ensuring the proper operation of electrical systems. The other measurements available on a DMM, such as voltage, resistance, and frequency, serve different functions and do not relate to the capacitance measurement. They assess different electrical parameters that are critical in diagnosing and working with electrical systems but are not interchangeable with capacitance measurements.
