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.\n\nWith 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.\n\nThe 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.\n\n* 1 coulomb is equal to 6.25*10^18 electrons.\n\nAll neutral atoms have the same number of electrons and protons.\n\n== External links ==\n\n* [[Wikipedia:Electric charge]]\n\n{{Page data\n| license = CC-BY-SA-3.0\n| description = Electric charge is at the core of circuits.
