• Atomic particles (protons and electrons) carry positive and negative electrical charges.
• Like charges repel while opposites attract.
• In general objects have equal + and – charge.
• Electrons move easily so objects may become charged by frictional contact.
• Van de Graaff generator’s dome can collect charge and raise it to a very high potential.
• Electrical potential (volts) indicates energy per charge, similar to temperature which indicates energy per molecule.
