Electricity and electronic Electricity: Type of energy between particles that generate a force of attraction or repulsion. Electronics: Is the branch of physics that studies the control of the movement of electrons in semi-conducting materials. Circuit : An electrical circuit is a complete route which an electric current can flow around. -Types of components -Power sources: The elements that supply the electrical energy needed for the electrons to move through the circuits. ln direct current circuits, the power sources are batteries; in alternating current circuits, they are alternators. -Load devices: These elements receive the electrical energy from the power sources.Load devices include motors, lamps, resistors, etc. -Conductors: These components transport the electric current from the power sources to the load devices. Wires are an example of conductors. -Control and protection elements: The elements that operate the circui...
