Which of the following is not a type of variable that a multimeter can measure?

• A. Voltage
• B. Current
• C. Resistance
• D. Light intensity

Answer: (D)

A multimeter is a versatile instrument primarily designed for measuring electrical quantities: voltage, current, and resistance. Voltage measurement allows the user to determine the potential difference between two points in an electrical circuit. This is essential for checking the functionality of devices and power sources. Current measurement enables users to assess the flow of electric charge, which is vital for ensuring that circuits are operating within their intended parameters. Resistance measurement helps in identifying issues within circuits, like shorts or breaks, by allowing users to measure how much the circuit impedes the flow of electricity. In contrast, light intensity is not an electrical measurement directly associated with a multimeter’s primary functions. It is usually measured with specialized equipment like light meters or photometers designed for that specific purpose. Thus, light intensity does not fit the category of measurements that a standard multimeter is built to handle.
