Electric charge is a physical property. It occurs between particles or objects. It causes them to attract or repel each other. They do not even have to touch. This is unlike the typical push or pull you may be familiar with. All electric charge is based on the protons and electrons in atoms. A proton has a positive electric charge. An electron has a negative electric charge. Forces on Charged Objects Most atoms are balanced electrically. They have the same number of positive and negative charges. Therefore, the number of protons equals the number of electrons. Neutrons do not matter as they have no charge. When an object loses some electrons, it becomes positively charged. There are now more protons than electrons inside the atom. The lost electrons may remain free. Or, they may attach to another object. The new object now has more electrons than protons. It then becomes negatively charged.

What causes objects to attract or repel each other?
Elektrisk laddning är en fysisk egenskap. Den förekommer mellan partiklar eller föremål. Det får dem att attrahera eller stöta bort varandra. De behöver inte ens röra. Detta är till skillnad från den typiska push eller dra du kan vara bekant med. All elektrisk laddning är baserad på protonerna och elektronerna i atomer. En proton har en positiv elektrisk laddning. En elektron har en negativ elektrisk laddning. Krafter på laddade objekt De flesta atomer balanseras elektriskt. De har samma antal positiva och negativa avgifter. Därför är antalet protoner lika med antalet elektroner. Neutroner spelar ingen roll eftersom de inte har någon laddning. När ett objekt förlorar vissa elektroner blir det positivt laddat. Det finns nu fler protoner än elektroner inuti atomen. De förlorade elektronerna kan förbli fria. Eller också kan de fästa vid ett annat föremål. Det nya objektet har nu fler elektroner än protoner. Den blir sedan negativt laddad. Har du några frågor?
