The circuit diagram is the ideal way to show the design of the circuit. They show the exact picture of the original object and gives clear information about the circuit. The diagram helps with easy understanding of the flow of current and the components that are connected to it. Included in this diagram are circuit symbols such as wires, lamps, cells, fuse, and batteries. But there are a variety of lines that are used to show the connection between objects. The circuit diagram provides an efficient and a trouble-free way to explain how an electrical circuit works in visual representation.
