Static and Current Electricity
How to design a complete, simple circuit?
A complete circuit must have a power source (battery) and a path for the electric current, such as a wire, to flow through. For the energy to flow and create an electric current, the circuit must be closed. This means the path along which the electrical current flows must not be broken or opened anywhere along the way. When a light is turned on in your classroom, an electrical circuit is closed with a switch. This allows the electric current to complete its path and flow through the wire to the bulb. When we flip the switch off, we open the circuit and stop the flow of the electricity. This is called an open circuit.
Conductors and Insulators
Conductors and Insulators
Conductors of electricity allow an electric current to flow. Metals such as copper, silver, and aluminum are conductors. Conductors, such as metal wires, are used in electric circuits. Materials that do not allow electrons to flow are insulators. Examples of insulators include glass, rubber, and plastic. Electric cords have rubber insulation wrapped around the cord and plug to prevent electric shock. Wall sockets have plastic plates surrounding the outlet that serve as insulation and protect people from electric currents.
