Which of the following measurements are made using a multimeter?

• A. Voltage and capacitance
• B. Voltage and current
• C. Voltage and resistance
• D. Current and frequency

Answer: (C)

A multimeter is a versatile instrument commonly used in electronics for measuring various electrical properties, including voltage, current, and resistance. When it comes to the specific measurements regarding voltage and resistance, a multimeter can accurately measure both parameters, providing critical information for troubleshooting and verifying electrical circuits.

In terms of functionality, when measuring voltage, the multimeter is set to the appropriate setting (AC or DC) and probes are connected across the component or circuit point of interest. For resistance measurements, the multimeter applies a small voltage to the resistor and measures the resulting current to calculate resistance using Ohm's law (V = IR).

While some multimeters can measure capacitance and current, the essential measurements that all multimeters are designed to perform are voltage and resistance. This makes the combination of voltage and resistance a fundamental aspect of using a multimeter effectively in a variety of electrical applications.
