A digital multimeter is electronic test equipment that can perform multiple tasks. Which description best matches its typical capabilities?

• A. Measures only voltage
• B. Measures humidity
• C. Generates signals
• D. Measures voltage, current, and resistance (and sometimes capacitance, inductance, and transistor gain)

Answer: (D)

A digital multimeter is a versatile electrical tester designed to measure several basic electrical quantities. Its standard tasks include measuring voltage, current, and resistance, which cover most common troubleshooting needs in circuits. Many models also add capabilities beyond these basics, such as measuring capacitance and inductance, and sometimes determining transistor gain, making it even more useful for diagnosing components. It’s not used to measure environmental conditions like humidity, and generating signals is the job of a signal generator, not a multimeter. So the description that matches most closely is one that lists voltage, current, and resistance as core functions, with the possibility of additional measurements on more advanced models.
