A feature commonly found on many digital multimeters is the ability to measure

• A. Capacitance measurement
• B. Sinusoidal measurement
• C. Resistance measurement
• D. Pulse measurement

Answer: (A)

Capacitance measurement is a common feature on digital multimeters because capacitors are everywhere in circuits and knowing their value is essential for timing, filtering, and energy storage tasks. To measure capacitance, the meter applies a small, known excitation (such as a brief current pulse or a low-frequency AC signal) and observes the capacitor’s response. Using the relationship between current, voltage, and time (for example I = C dv/dt or the impedance Xc = 1/(2πfC) at a fixed frequency), the meter calculates the capacitance. This lets you quickly verify capacitor values or detect bad components (open, leaky, or shorted) without removing them from the circuit. Other options aren’t as universally provided on many DMMs: sinusoidal measurement isn’t a standard standalone function on most, pulse measurement isn’t typical, while resistance measurement is common but measures a different property and doesn’t address capacitor verification directly.
