The current, I and the resistance, R. Electrical current, I is the flow rate of electric charge in electric field, usually in electrical circuit. Electric charge is carried by charged particles, so an electric current is a flow of charged particles. Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it. The resistance is measured in units of ohms (). If we make an analogy to water flow in pipes, the resistance is bigger when the pipe is thinner, so the water flow is decreased. b. The single-phase system and three-phase system. In electrical engineering, single-phase electric power is the distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison. Single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors. The system which has three phases, i.e., the current will pass through the three wires, and there will be one neutral wire for passing
