How are circuits used by professionals in Industry?

Question

This is part of my science coursework, thanks

Answer 1

There are millions and millions of circuits on a computer chip. Most every professional in in Industry uses a computer (which has a computer chip).

In response to below a "gate" is considered a circuit. There are millions and millions of gates on a computer chip -> there are millions and millions of circuits on a computer chip.


Also an EE.

Answer 2

I answer this question the way I understand what has been asked....
In the 60's, an electronic engineer actually had to know how a transistor works, and had to construct the simplest of circuitries from scratch, using only basic components like transistors, diodes, resistors, capacitors, etc...
Nowadays (in my personal opinion), electronic engineers have been somewhat "reduced" to Application Engineers, because there are thousands of integrated circuits available which do not only do most commonly used functions (logic gates, timers, amplifiers, regulators, just to name a few), but also very complex ones, like video processors, radio receiver-in-a-chip, and of course microprocessors.
Those circuits contain hundreds, sometimes thousands of components.
What the "professional" nowadays has to do is know what Integrated Circuits are on the market, and how to wire them together in order to achieve the total required functionality.

Answer 3

A very broad topic. There are not millions and millions of circuits on a computer chip as reported by one respondant, there are hundreds of components. It is called an "integrated circuit". In general, every device that operates on electricity involves an electrical circuit. Even a simple light has circuits providing a power source.
In industry, there are complex control circuits operating machines and factories.
