What device is used to measure static electricity?

• A. Electromagnetic field meter
• B. Thermocouple
• C. Electrostatic voltmeter
• D. Sound level meter

Answer: (C)

The electrostatic voltmeter is specifically designed for measuring static electricity and is used to determine the electrical potential difference between an object and a reference point, typically ground. This device operates based on the principle of electric field measurement, enabling it to detect and quantify static charges even at low levels. It is crucial in environments where static electricity can cause damage or interference, such as in electronics manufacturing or handling sensitive components. In contrast, an electromagnetic field meter measures electromagnetic fields, which does not pertain to static electricity. A thermocouple is used for measuring temperature, while a sound level meter gauges sound intensity, making them unsuitable for measuring electrical charge. Therefore, the electrostatic voltmeter is the appropriate choice when tasked with measuring static charge levels.
