In MKS system, the unit of current is:
Correct answer: A. Ampere
- A. Ampere
- B. Volt
- C. Coulomb
- D. Ohm
Explanation
The ampere (A) is the unit of electric current in the MKS system. One ampere is defined as one coulomb of electric charge flowing per second through a conductor. It is a fundamental unit in the International System of Units (SI) and is used to measure the rate of flow of electric charge in a circuit.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
