I have worked on an example earlier today. It's the section on BJT Amplifiers.(adsbygoogle = window.adsbygoogle || []).push({});

I have been studying the sub-section on Common-Collector Amplifier. I've come across a rather peculiar formula, which has not been mentioned anywhere in my prescribed textbook besides a worked example.

Here is the formula:

R_{e}= R_{E}|| R_{L}

I am pretty much confused about the application of this formula.

Can the formula be used in a Common-Emitter circuit?
