a) protons
b) neutrons
c) electrons
d) ions
What is the SI unit of charges?
a) Candela
b) Ohm
c) Coulomb
d) Ampere
Explanation:The coulomb (symbol: C) is the unit
of electric charge in the International System of
Units (SI).
The SI defines the coulomb in terms of
the ampere and second: 1 C = 1 A × 1 s.
