Which function is not typically provided by a digital multimeter?

• A. Measuring voltage
• B. Measuring sound level
• C. Measuring current
• D. Measuring resistance

Answer: (B)

A digital multimeter is designed to measure electrical properties by sensing and converting electrical signals into a readable value. It expects to handle volts (AC or DC), current (by placing the meter in series and measuring the flow), and resistance (by applying a small test current and checking the resulting voltage). It’s built with input circuitry and an ADC tailored to these electrical quantities, plus features like continuity and sometimes capacitance or frequency. Measuring sound level, on the other hand, is an acoustical task. It requires a microphone to capture sound pressure and specialized processing (weighting filters, calibration, and decibels) to convert that physical sound into a meaningful level. A standard digital multimeter doesn’t include a microphone input or the software and calibration needed for sound level measurements, so this capability isn’t typically provided. So the function that isn’t typically available on a digital multimeter is measuring sound level, while voltage, current, and resistance measurements are standard capabilities.
