2 cards from this section. Quick, good the night before a test.
What is output resistance?
Think about how it affects loads.
What does KCL stand for?
It governs current flow at junctions.
What does output resistance affect in an amplifier?
Consider the entire interaction with the load.
True or False: KCL states that all currents at a junction must leave it.
Think about how currents balance.
A common collector amplifier has an output resistance of 50 ohms. What happens if you change the load to 150 ohms?
Apply voltage division principles to find new output conditions.
Analyze how increasing the collector resistance from 100 ohms to 500 ohms affects voltage gain and output resistance.
Evaluate the relationship between voltage gain and change in output resistance.
