**ELECTRICITY** **Circuit** - The electric circuits are closed-loop or paths, forming a network of electrical components where electrons can flow. This path is made using electrical wires and is powered by a source, like a battery. The start of the point from where the electrons starts flowing is called the source, whereas the point where electrons leave the electrical circuit is called the return. **Electric Circuit Symbols** Every component and product of the electric circuit contains a symbol. The symbols represent parts of the circuit in a circuit diagram. Beneath are the basic set of symbols that are present in a circuit diagram. **Simple Circuit** A simple circuit comprises the power source, conductors, switch, and load. - **Cell:** It is the power source. - **Load:** It is also termed as the resistor. It is a light bulb that lights when the circuit is turned on. - **Conductors:** They are made of copper wires with no insulation. One end of the wire is connected to the load to the power source, and the other end of the wire connects the power source back to the load. - **Switch:** It is a small gap in the circuit. A switch can be used to open or close a circuit. **Series Circuit** A circuit is said to be connected in series when the same current flows through all the components in the circuit. In such circuits, the current has only one path. Household decorative string lights are an example of a series circuit. This is nothing but a series of multiple tiny bulbs connected in series. If one bulb fuses, all the bulbs in the series do not light up. **Parallel Circuit** A circuit is said to be parallel when the electric current has multiple paths to flow through. The components that are a part of the parallel circuits will have a constant voltage across all ends.
