Electricity is the flow of electrons in a closed circuit.\ Current electricity involves the flow of electrons through a conductor.\ ACSR is Aluminum Cable Steel Reinforced.\ Franklin discovered that lightning and static electricity were the same phenomenon.\ Electricity produced from magnetism requires the movement of a coil and a magnet.\ Protons carry a positive charge and are located in the nucleus of an atom.\ Matter is composed of atoms, and atoms consist of electrons, protons, and neutrons.\ Insulators are materials that do not allow electric charges to move freely.\ The resistance of a material increases as its temperature increases.\ Electrons are lighter than protons and carry a negative charge.\ In an open circuit, current cannot flow between two disconnected terminals.\ Georg Ohm is known for formulating the law that relates current, voltage, and resistance.\ A short circuit occurs when the resistance between two terminals is very low.\ Direct current (DC) flows in one direction only, while alternating current (AC) changes direction periodically.\ Electrons in the outermost shell of an atom are known as valence electrons.\ Silver is a better conductor of electricity than copper.\ The unit of resistance is the ohm (Ω\\Omega).\ In a conventional current flow, current moves from the positive terminal to the negative.\ Electric current is the flow of electrons through a conductor.\ The SI unit for voltage is the volt.
