How physics applied electronics??

Answer 1

I have seen this question asked many times before and wonder why it keeps on getting asked... I assume if could be that the asker is considering a career in electronics but may not be very good at physics and may be wondering how important physics is in the field of electronics.

Ok so assuming this is the case, the answer I offer is this:

The amount of "physics knowledge" involved in working in electronics is actually very little. Yes you need to understand basic electron theory for the purpose of understanding current flow and silicon junctions, ohms law etc, but it is more mathematics and formulas that are needed for the design of electronic equipment as well as the ability to read and interpret schematics and technical data.

Answer 2

How physics is applied to electronics?  I believe is the question.

Physics describes in mathematical terms how circuits and circuit components operate both structurally and at the atomic level. This is very important in designing systems that involve many, many transistors on a chip, for example. Physics helps engineers design and build "models" of how complex networks should operate under varying environmental conditions, for example.  It is physics that tells the designer how a photomultiplier tube operate and, more importantly, why it functions at all.  Physic tends to look at the mathematics and small details of why an electronic system performs in a given fashion; while engineering tends to focus on the interfacing of components and stages to create an efficient system that does a particular function.

Physics, in my opinion, is the basic unit of all science and engineering.  If you are to truly understand electronics engineering, you must first understand something about physics, especially classical and quantum physics.

Your question dosent make sense. What do you mean?
