Printed circuit board Electrical Circuit with an IC.. Electronic engineering is a sub-discipline of electrical engineering that emerged in the early 20th century and is distinguished by the additional use of active components such as semiconductor devices to amplify and control electric current flow.
The following outline is provided as an overview of and topical guide to electronics: Electronics – branch of physics, engineering and technology dealing with electrical circuits that involve active semiconductor components and associated passive interconnection technologies.
The basic components of analog circuits are wires, resistors, capacitors, inductors, diodes, and transistors. Analog circuits are very commonly represented in schematic diagrams , in which wires are shown as lines, and each component has a unique symbol.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
It revolutionized the electronics industry, [20] [21] becoming the most widely used electronic device in the world. [22] [23] The MOSFET is the basic element in most modern electronic equipment. [24] [25] As the complexity of circuits grew, problems arose. [26] One problem was the size of the circuit. A complex circuit like a computer was ...
Diode load line. The curve shows the diode response (I vs V D) while the straight line shows the behaviour of the linear part of the circuit: I=(V DD-V D)/R.The point of intersection gives the actual current and voltage.
Principles of Electronics is a 2002 book by Colin Simpson designed to accompany the Electronics Technician distance education program and contains a concise and practical overview of the basic principles, including theorems, circuit behavior and problem-solving procedures of Electronic circuits and devices.
