5 fundamental circuit components or functions and what are some safety functions that are performed in most practical power circuits????

thanks:)

Can you name ANY of the components in the above circuit diagram?

Ground is a component? When did 'power supply' become a component? It is a collection of components usually used to convert one type of electrical power into another.

Good.

Yes, all except the power supply are components.

The power supply is more like the function of the components in the lower circuit, just like the top circuit is an amplifier.

You could add switch, transformer, LED, potentiometer (also a trim pot which is often a screwdriver adjustment) , integrated circuit, electrolytic capacitor.

It would not be unusual to find a fuse in series with the power switch.

Note that some of the transistors are NPN while others are PNP. You can tell by which way the arrow is pointing on the emitter symbol. Q1 and Q4 are NPN and the others are PNP.

Not shown are FETs and MOSFETs which are also important.
