3 cards from this section. Quick, good the night before a test.
What does a current amplifier output?
Remember, it's not voltage.
What is DC bias?
Think about operating points of BJTs.
What is the output of a current amplifier?
Think of its name.
True or False: An unloaded current gain is affected by the load connected.
Reflect on the definition of 'unloaded'.
If a current amplifier has an unloaded gain of 10 and the input current is 2mA, calculate the output current when a load of 1kΩ is connected and the output resistance is 500Ω.
Use the unloading current formula while accounting for output resistance.
Design a lab experiment to visualize the effect of varying load resistance on output current in a current amplifier. Include method and expected outcomes.
Consider using a multimeter for reading output current.
