4Question 4.
True or False: The unloaded current gain is affected by connected loads.
- True
- False
Show hintHide hint
Recap what loading effects do in amplifier circuits.
Question 5.
Design a current amplifier with a specified unloaded current gain of 10. Choose appropriate components and justify your choices.
Show hintHide hint
Use the relationship of current gain to calculate biasing conditions.
Question 6.
Given a current amplifier produces an output current of 5 mA with 0.5 mA input current, what is the unloaded current gain? What does this tell us about the amplifier?
Show hintHide hint
Remember the formula for calculating gain.
