What are three engineering facts that every electronics engineer should know?

Electronic Engineering is a discipline of electrical engineering where non-linear and active electrical components are used to design electronic devices, circuits, VLSI devices, and their systems. The active electronic components consist of semiconductor devices such as diodes, transistors, and IC (Integrated Circuits).

Every electronics engineering must know the three basic engineering facts mentioned below

1. Electronics is a branch of Electrical Engineering

Electrical engineering generally comprises of five elements

1. Generation (V)
2. Transmission (I)
3. Utilization (R)
4. Measurement (V=IR & P=VI)
5. Control

The fifth element differentiates electrical and electronics. When the control is manual such as switch and regulator, it falls under mechanical engineering. When the control is automatic through relays, it falls under electron magnetics. On the other hand, when the control is automatic through vacuum tube transistors, it falls under electronics.

1. Substitutes for Transistor, Gate, and Amplifier

Every electronics engineer should know the originality of transistors, gate, and amplifiers.

1. A transistor is just a variable resistor.
2. A gate is just a switch.
3. An amplifier is just a regulator

III. The truth behind IC’s

An Integrated Circuit (IC) is a simple implementation of circuits inside silicon boards. It is similar to a circuit board. Multiple transistors are placed on Integrated Circuit. Currently, the count of transistors placed inside an Integrated Circuit has exceeded 10,000,000,000, where the size of each transistor is around 10nm (nanometer).

1 nm = 1/1000000 mm
