What is an Electronic Circuit What is an Electronic Circuit Design?Design?
It is a plan or drawing produced to show the look and function or workings of an electronic circuit.
What is an Electronic Circuit ?What is an Electronic Circuit ?
An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors, ICs and diodes, connected by conductive wires or traces through which electric current can flow.
