alleryStart learning →The SI unit of electric charge is the:
- volt
- ampere
- coulomb
- ohm
Show answer and solution
Correct answer: C. coulomb
Charge is measured in coulombs (C). 1 C = 1 A·s.
The fundamental unit of charge is e = 1.6 × 10⁻¹⁹ C (proton/electron magnitude).

syllabus names exactly three basic properties: quantisation, additivity and conservation.
Naming them is easy; telling them apart is the actual skill.

- Quantisation means the total charge of a body is always an {0} of the basic quantum e. A proton carries {1} and an electron carries {2}.
Charge is granular, and the grain is e. Source: syllabus Physics Part I, Ch 1 Electric Charges and Fields.
