4 cards from this section. Quick, good the night before a test.
What does a current amplifier do?
Think about how input and output signals relate.
What is an unloaded current gain?
Consider what happens when no external resistor is connected.
What is the primary function of a current amplifier?
Focus on the definition of current versus voltage amplification.
True or False: Unloaded current gain measures amplification with load connected.
Recall the definition of 'unloaded' in amplification.
Design a current amplifier system with specific parameters, including an input current of 10mA, an unloaded current gain of 5, and an output resistance of 1kΩ. What is the expected output current and how does the load affect it?
Consider the circuit as a loading effect and see how the output changes with different load resistances.
If you were to connect two current amplifiers in series with the output of the first serving as the input of the second, how would you analyze this combined configuration in terms of current gain and loading effects?
Focus on how each amplifier's characteristics can interact through their loading effects.
