Circuits
Series vs. Parallel
Vocabulary
• Circuit• Energy Source• Load• Conductor
• Resistor• Switch• Series Circuit• Parallel Circuit
Circuits
• A circuit is a path through which electricity can flow.
• Charges flow in a circuit when there is a potential difference.
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.
Circuits
Circuits
• Energy Source– Used to push a charge through a circuit– Ex: batteries
• Loads– Devices in a circuit that operate using
electrical energy– Ex: light bulb, toaster, and motors
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.
