Which of the following tools is essential for measuring electrical voltage?

Clamp meter
Multimeter
Oscilloscope
Signal generator

The correct answer is: Multimeter

A multimeter is essential for measuring electrical voltage because it is specifically designed to measure various electrical properties, including voltage, current, and resistance. It provides direct readings of voltage levels, allowing technicians to assess whether voltage is within the expected range in circuits or components. Multimeters often have multiple ranges, which enables users to measure both low and high voltages accurately. The clamp meter, while useful for measuring current without breaking the circuit, does not directly measure voltage. An oscilloscope is utilized primarily for visualizing voltage waveforms over time, making it valuable for analyzing signals but not for direct voltage measurements in a straightforward manner. A signal generator is a device that creates oscillating electrical signals and is used for testing and experimentation, not for measuring voltage. Thus, in the context of tools specifically for measuring electrical voltage, the multimeter is the appropriate choice.
