VFPt charges plus minus thumb.svg

There are only two types of electric charge (positive and negative). These charges are equal in size, but different in character. They are denoted as positive (+) and negative (-). A charge exist between any two objects that have a net charge. To calculate the net charge, sum together the positive and negative charges.

With electric charges, like charges repel each other, and unlike charges attract each other. So a positive charged object would attract a negatively charged object and would repel a positively charged object.

The unit of charge is called a Coulomb. The protons have a positive charge, while the electrons have a negative charge. The protons positive charge is equal in size to the electrons. It is possible to have a neutral atom but this would require the same number of electrons and protons.

  • 1 coulomb is equal to 6.25*10^18 electrons.

All neutral atoms have the same number of electrons and protons.
