Ohm x Farad is equivalent to:
Correct answer: A. Second
- A. Second
- B. Weber
- C. Henry
- D. Tesla
Explanation
The product of Ohm (unit of resistance) and Farad (unit of capacitance) results in the unit of time, which is the second. Therefore, option a is correct.

About Dimensional Analysis
Dimensional analysis expresses physical quantities through fundamental dimensions such as mass, length and time. It checks dimensional consistency, helps derive relations and converts between unit systems, but cannot determine numerical constants or distinguish quantities with identical dimensions. Dimensional formulae must not be confused with complete physical units.
