What is a multimeter, and what does it measure?

A multimeter is an essential electronic instrument that can perform multiple measurements, making it a valuable tool for various electrical applications. The correct choice identifies that a multimeter measures voltage, current, resistance, and continuity.

• Voltage measurement allows users to assess the electrical potential difference between two points in a circuit, which is crucial for troubleshooting and design.

• Measuring current helps determine how much electrical flow is present, important for ensuring that components operate within safe limits.

• Resistance measurement is vital for checking the integrity of components, such as resistors and connections, to ensure there are no breaks or faults.

• Continuity testing is used to verify that a circuit is complete, which is crucial for diagnosing faults in wiring or components.

Overall, the versatility of a multimeter makes it indispensable for both professional electricians and hobbyists, enabling comprehensive testing and analysis of electrical systems. This multi-function capability distinguishes it from devices that are limited to measuring only one type of electrical parameter, such as voltage or current alone.
