Hi. This is a problem from an electronics textbook:
The output voltage of a voltage amplifier has been found to decrease by 20% when a load resistance of 1 k is connected. What is the value of the amplifier output resistance?
How is there an output voltage without there being a load? 80% compared to what?
The answer is 250 Ohm.
Thank you.
