The dimension of the volt is:
AJ / C as a ratio
BC / J as a ratio
CN · C as product
DJ · C as product
Answer & Solution
Correct answer: A. J / C as a ratio
1. Potential difference = energy per unit charge = J / C.
2. So 1 V = 1 J / 1 C.
3. This is what 'volt' fundamentally means: the work done in moving 1 C of charge through 1 V is 1 J.
