What unit is used in the International System of Units to measure electric potential difference?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Volt
The International System of Units (SI) employs the volt (V) as the standard unit for measuring electric potential difference. One volt is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power. Electric potential difference, often referred to simply as voltage, is crucial in understanding the flow of electric charge in circuits and the operation of electrical devices. It is symbolized by the letter "V" in equations and circuit diagrams.
