What is the unit of electric potential?

Last Updated: 25 Jun 2026

What is the unit of electric potential? Here, the relevant answer is “Volt.” A sound solution relies on the governing concept rather than a memorised option letter, because option order may change in another paper. While reading a question, first note whether it asks for a definition, SI unit, formula, direction, cause, effect, or practical use. The distractors in this question—Ampere, Coulomb, Ohm—do not satisfy the exact condition stated. Students should therefore read every qualifier, including words such as “always,” “at infinity,” “in vacuum,” “per unit,” and “directly proportional.” Such words often decide the correct option. Revise the definition, symbol, SI unit, formula, and one everyday example as a single learning set.

Correct Answer: VoltYour Answer: C

Explanation

— the scientifically appropriate response is Volt. Option-wise review: Volt is correct under the condition given in the stem. Ampere is incorrect because it describes a different quantity or phenomenon and does not meet the stated condition. Coulomb is also incorrect; although it may be a valid physics term, its definition or application is not the one asked here. Ohm is incorrect because it fails the governing relation or characteristic relevant to this case. Identify the chapter, recall the exact definition or equation, check the unit or direction if applicable, and then eliminate choices that contradict it. Therefore, option C, Volt, is factually and logically consistent with the question. Electric potential is measured in Volts (V).

Important Notes

Read the complete stem before looking at the options. Identify whether the demand is a definition, unit, formula, direction, cause, effect, image characteristic, or device principle. In this record, the confirmed answer is Volt.
Learn each concept as a five-part card: definition; common symbol; SI unit; principal equation; and one real-life application. This works for mechanics, heat, optics, sound, electricity, magnetism, and modern physics.
Do not interchange closely related terms: mass and weight; distance and displacement; speed and velocity; heat and temperature; reflection and refraction; real and virtual image; current and potential difference; power and energy. Such pairs generate common SSC distractors.
Eliminate Ampere, Coulomb, Ohm here because none fulfils the exact requirement of the stem. The final answer and correct-index field must point to option C.
Exam memory point: connect Volt directly with the key wording of the question, then verify it once against the relevant definition or formula before marking the answer.Named after Alessandro Volta

FAQ

SSC CGL Physics FAQs

Common questions and clear answers for this topic.

How many physics questions usually appear in the SSC CGL exam?

Physics typically makes up a small portion of the General Science questions, usually focused on concepts rather than numerical problems.

Which physics topics are most important for SSC CGL?

Basic mechanics, heat, sound and light, and electricity and magnetism are the areas that come up most consistently across previous papers.

Do I need to solve numerical problems for SSC CGL physics?

Rarely. Most questions are conceptual and test everyday understanding rather than calculation skills.

Is NCERT physics enough for SSC CGL preparation?

NCERT textbooks from classes 9 and 10 build a strong enough conceptual base for most of what SSC CGL asks.

How can I make physics concepts easier to remember for SSC CGL?

Connecting concepts to everyday observations, like why a thermos keeps tea warm, makes them far easier to recall than memorizing definitions.
