What is a multimeter, and what does it measure?

• A. It is a device that only measures voltage
• B. An electronic instrument that can measure voltage, current, resistance, and continuity
• C. A type of circuit breaker used to measure power
• D. It only measures current in a circuit

Answer: (B)

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.
