Which of the following does a standard multimeter not measure?

A standard multimeter is a versatile tool primarily used for measuring electrical parameters such as voltage, current, and resistance. Each of these functions allows users to assess different aspects of electrical circuits.

Voltage measurement allows users to determine the electrical potential difference between two points, essential for understanding circuit behavior. Current measurement provides insight into the flow of electric charge through a circuit, indicating how much electricity is being consumed by components. Resistance measurement helps users evaluate how much opposition is present in a circuit, further guiding troubleshooting and design.

While multimeters can perform various measurements, including frequency under certain conditions, not all standard multimeters include this capability as a primary function. Basic models typically do not have a frequency measurement function, which is commonly found in more specialized or advanced multimeters. Therefore, selecting frequency as the answer reflects the understanding that it is not a standard measurement provided by typical multimeters, distinguishing it from the other three fundamental electrical properties these devices measure regularly.
