2 cards from this section. Quick, good the night before a test.
What is the main function of a voltage amplifier?
Think about what amplification means.
What type of signals do we focus on when analyzing amplifiers?
Remember the context of input signals.
What is the role of a voltage amplifier?
Think about what we want to achieve with amplification.
Is the loading effect beneficial for voltage gain?
Consider how connecting a load impacts the circuit.
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?
Use the voltage gain formula.
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.
Consider how load interacts with the gain.
