About the Subject :
An electronic circuit is composed of individual electronic components,
such as resistors, transistors, capacitors, inductors and diodes, connected by
conductive wires or traces through which electric current can flow. The
combination of components and wires allows various simple and complex
operations to be performed: signals can be amplified, computations can be
performed, and data can be moved from one place to another.
