A circuit is a path for electricity to flow and contains an energy source, loads, and conductors connecting them. There are two main types of circuits: a series circuit where all components are connected one after the other so current flows through each in sequence; and a parallel circuit where components are connected side by side so current divides and flows through each component simultaneously.

1. Circuits Series vs. Parallel

2. Vocabulary Circuit Energy Source Load Conductor Resistor Switch Series Circuit Parallel Circuit

3. Circuits A circuit is a path through which electricity can flow. Charges flow in a circuit when there is a potential difference.

4. Circuits Most circuits have three parts: an energy source , one or more loads , and conductors (wires) that connect the two. Circuits may also have a switch that can be opened or closed to allow or stop the flow of current Energy flows only through a closed circuit.

6. Circuits Energy Source Used to push a charge through a circuit Ex: batteries

7. Loads Devices in a circuit that operate using electrical energy Ex: light bulb, toaster, and motors

8. Circuits Conductors Material that allows electrical energy to flow through it easily. Ex: wires Wires carry electrical current from the energy source to the load that is apart of the circuit.
