When measuring voltage in an AC circuit, what type of meter should be used?

A digital voltmeter is the appropriate tool for measuring voltage in an AC circuit due to its design and functionality. Digital voltmeters are specifically engineered to provide accurate readings of both AC and DC voltage. They utilize digital displays, which make it easier to read the measurement without the fluctuations that can occur with analog displays.

In addition, digital voltmeters often feature a higher input impedance compared to analog meters, minimizing the load on the circuit being measured and ensuring that the voltage measurement is not affected by the meter itself. This characteristic is particularly important in AC circuits, where maintaining the integrity of the circuit's performance is crucial for obtaining accurate readings.

While analog ohmmeters, clamp meters, and amperage meters are useful for other measurements—such as resistance and current—they are not designed for measuring voltage directly in an AC circuit. The specific capabilities and design of the digital voltmeter make it the best choice for this application, ensuring reliable and precise voltage measurements.
