7 Student Resource: Circuit Basics Simple Circuit A simple circuit consists of three minimum elements that are required to complete a functioning electric circuit: a source of electricity (battery), a path or conductor on which electricity flows (wire) and an electrical resistor (lamp) which is any device that requires electricity to operate. The illustration below shows a simple circuit containing, one battery, two wires, and a bulb. The flow of electricity is caused by excess electrons on the negative end of the battery being attracted to flow toward the positive end, or terminal, of the battery. When the simple circuit is complete, electrons flow from the negative terminal through the wire conductor, then through the bulb (lighting it up), and finally back to the positive terminal - in a continual flow. Schematic Diagram of a Simple Circuit The following is a schematic diagram of the simple circuit showing the electronic symbols for the battery, switch, and bulb.
