This is a simple circuitA collection of wires and electric components connected together in such a way that electric current can flow through them..
Electric currentElectric current is a flow of electric charges (electrons). flows equally through all parts of the circuit. As the current flows through the bulb it lights up. The voltage produced by the batteryA battery is two or more electric cells joined together that can produce an electric current when connected to an electric circuit. pushes the current around the circuit.
Electricity flows best through good conductorsConductors are materials that carry electric current really well. like metals. The wires used in circuits are made of copper metal covered in plastic. Plastic is a good insulatorA material that reduces or stops the flow of electric current..
