What are the most common functions of a generic multimeter?

The choice highlighting the functions of a generic multimeter correctly identifies the voltmeter, ammeter, and ohmmeter as its most common functionalities.

A multimeter is a versatile instrument used in various electrical measurements. As a voltmeter, it measures the electrical potential difference between two points in a circuit, which is crucial for diagnosing issues in electrical systems. As an ammeter, it measures current flow through a conductor, allowing for the assessment of circuit functionality and troubleshooting. The ohmmeter function measures resistance, providing valuable information about the integrity of electrical components and connections.

These three functions form the core capabilities of a generic multimeter, making it an essential tool for electricians and technicians in the field, as they can perform a range of diagnostics and measurements with a single device. Other options, while they contain related equipment or features, do not accurately represent the primary functions of a standard multimeter.

For instance, signal generators and power supplies are separate devices used for specific functions, such as providing voltage signals or supplying power to circuits, while capacitance and inductance meters focus on measuring specific components rather than providing the comprehensive versatility that a multimeter offers.
