Symbol:(q)
Unit: Coulomb (C)
- The fundamental electric quantity is charge.
- Atoms are composed of charge carrying particles: electrons and protons, and neutral particles, neutrons.
- The smallest amount of charge that exists is carried by an electron and a proton.
- Charge in an electron:
qe = -1.602×10-19 C
- Charge in a proton:
p = 1.602×10-19 C
