To Colin55:
It´s really unbelievable!
You have quoted some selected parts of my thread replies on your web page under the headline: SPOT THE MISTAKES.
However, at the moment, I do not care if this is an allowed procedure or not.
Something else is unbelievable: Somebody who claims that he was teaching electronics for 40 years thinks that the concept of "negative feedback" is identical with a "negative effect".
That means that he does not understand this term in a mathematical-technical but in a general and colloquial sense ("negative" identical to "bad").
I am speechless.
Quote from Colin´s web page:
But with the emitter follower arrangement we have a completely different set of circumstances.
We have an input signal that has full amplitude buy insufficient current to drive a load. To solve this problem we introduce a transistor that will amplify the current about 100 times.
How are you going to convince a beginner the load has a NEGATIVE EFFECT?
If the resistance of the load is increased, it will require less current and thus less current will be needed by the input signal.
How can this be a NEGATIVE EFFECT?
Question to Colin55:
Why do you think is the concept of "negative feedback" on of the most applied principle in analog electronics? Because it has so many "negative effects"?
Your columne is the best example for my recommendation to all beginners: Do never blindly trust everything you find in the web.
