22.1.3. Examples of Voltage Amplifiers

Try these first

1. 1.

   What is the main function of a voltage amplifier?

   Hint

   Think about what amplification means.

2. 2.

   What type of signals do we focus on when analyzing amplifiers?

   Hint

   Remember the context of input signals.

3. 3.

   What is the role of a voltage amplifier?

   • Increase current
   • Increase voltage
   • Decrease voltage

   Hint

   Think about what we want to achieve with amplification.

4. 4.

   Is the loading effect beneficial for voltage gain?

   • True
   • False

   Hint

   Consider how connecting a load impacts the circuit.

5. 5.

   If a voltage amplifier has a voltage gain of 10 and the input voltage is 0.5V, what is the output voltage without any load?

   Hint

   Use the voltage gain formula.

6. 6.

   In a scenario where connecting a 100 ohm load reduces the voltage gain from 10 to 8, calculate the effect on output voltage if the input remains 1V.

   Hint

   Consider how load interacts with the gain.
