Electrical and Electronics circuits are constructed using various components such as resistors, voltage/current sources, switches, and wires. Electrical circuits are visualized in papers and documentation work in the form of a circuit diagram. The circuit diagram represents the circuits using symbols instead of pictorial forms.
