22.1.5. Summary of Voltage Amplifier Concept

Try these first

1. 1.

   What is a voltage amplifier?

   Hint

   Think about what happens to the input signal.

2. 2.

   Define voltage gain.

   Hint

   It's how we quantify amplification.

3. 3.

   What does a voltage amplifier do?

   • A. Decreases the voltage
   • B. Increases the voltage
   • C. Converts AC to DC

   Hint

   Consider its primary function.

4. 4.

   True or False: Output resistance affects the voltage gain of the amplifier.

   • True
   • False

   Hint

   Think about load connections.

5. 5.

   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.

   Hint

   Use the voltage divider principle.

6. 6.

   Explain how reactive components can affect the performance of a voltage amplifier and provide an example.

   Hint

   Think about how these elements affect AC signals.
