3 cards from this section. Quick, good the night before a test.
What is a voltage amplifier?
Think about what happens to the input signal.
Define voltage gain.
It's how we quantify amplification.
What does a voltage amplifier do?
Consider its primary function.
True or False: Output resistance affects the voltage gain of the amplifier.
Think about load connections.
An amplifier has a voltage gain of 25 and is connected to a load of 100 Ohms. If the internal output resistance is 50 Ohms, calculate the actual output voltage when the input is 2V.
Use the voltage divider principle.
Explain how reactive components can affect the performance of a voltage amplifier and provide an example.
Think about how these elements affect AC signals.
