Charges & the Law of Conservation of Charges

• Static Electricity - a form of electricity produced when there is an imbalanced of electrical charges in or on the surface of an object.
• Static Electricity - Since the electric charges are not free flowing just like in a current electricity, static electricity is known as electricity at rest.
• Static electricity - The imbalanced charges on the surface of an object causes it to attract another object.
• American scientist Benjamin Franklin is known for his experiments on electricity. He first proposed that electricity is a fluid contained in matter.
• Benjamin Franklin - He was also the first person to use the terms positive and negative charges when used to describe electric charges in an object.
• Benjamin franklin - He gave the electron, a negative sign which has been the convention since then.
• An atom consists of three fundamental particles: electrons, protons, and neutrons.
• The proton and neutrons (collectively known as nucleons) are located in the nucleus.
• Though they have relatively small mass, the mass of the atom is contained in the nucleus. Revolving around the nucleus are electrons.
• Compared to the nucleons, electrons have a smaller mass.
• Inside the atom, protons are attracted to the electron. Both particles carry an electric charge.
• An electric charge (or simply charge) is a fundamental quantity of matter. It is usually denoted by a capital Q or a small letter q.
• The unit Coulomb (symbol, C) is commonly used to express the amount of electric charge.
• A proton has a positive charge while an electron has a negative charge.
• Electric charges behave just like magnets wherein like charges repel each other while unlike charges attract each other. This is called the principle of electric charges.
• two positive charges or two negative charges repel and a positive and a negative charge attract each other.
• According to the law of conservation of charges, electric charge is conserved.
• The sum of electric charges in any closed system is constant.
• Electricity, being a form of energy, is neither created or destroyed.
• Electric charges which generate electricity as they flow are neither created or destroyed too. Instead, charges are merely transferred from one object to another.
• Benjamin Franklin observed that during rubbing, charge is not created.
• Charge is only transferred from the rubbing material to the rubbed object or vice versa.
• An object’s net charge is the sum of the number of electrons and protons.
• A positively charged object has excess protons or deficiency in electrons.
• A negatively charged object has excess electrons or deficiency in protons.
• Static electricity is a form of electricity produced when there is an imbalanced of electrical charges in or on the surface of an object.
• A neutral object (or uncharged object) has an equal number of protons and electrons.
• An electric charge (or simply charge) is a fundamental quantity of matter. It is usually denoted by a capital Q or a small letter q.
• According to the law of conservation of charges, electric charge is conserved. The sum of electric charges in any closed system is constant. Charges are merely transferred from one object to another.
• An object’s net charge is the sum of the number of electrons and protons.
