What does electric charge represent? electric charge, basic property of matter carried by some elementary particles that governs how the particles are affected by an electric or magnetic field. Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed.
What does a positive charge represent? In an atom, a positive charge occurs when an atom has more protons than electrons. The proton is what determines its positive charge. It is denoted with a plus (+) sign. It attracts negative charges and repels other positive charges.
Does charge mean energy? Charge is wave amplitude at a given distance (r). It can be expressed as energy, but it is often expressed as a force, known as Coulomb’s law.
