+ <p style="justify-content: center"><strong> An electronic circuit consists of various electronic components like resistors, capacitor, diodes and transistors connected by a wire,
+ through which current flows in the circuit. Nowadays, instead of connecting the components through a wire, components are soldered to the interconnections which are created on the printed
+ circuit board (PCB) to form a finished circuit. A schematic circuit diagram is the representation of components and interconnections in a circuit using standardised symbols without using the
+ actual image of the component. Circuit diagrams are used for design, construction and maintenance of the electrical and electronic equipment. <br>
