Show hintHide hint
Think about what signals are amplified.
Question 2.
Name one key characteristic of voltage amplifiers.
Show hintHide hint
What type of signal does it work with?
3Question 3.
What does a current amplifier do?
- Amplifies voltage
- Amplifies current
- Does nothing
Show hintHide hint
Focus on the main function of the amplifier.
4Question 4.
True or False: Loading effects can increase output current.
- True
- False
Show hintHide hint
Consider how loads impact current distribution.
Question 5.
Given a current amplifier with an input current of 5 mA and an unloaded current gain of 10, calculate the output current.
Show hintHide hint
Look at how gain modifies the input current.
Question 6.
A current amplifier has a loading resistance of 50 ohms at the output and an internal resistance of 100 ohms. Given an unloaded output current of 60 mA, compute the actual output current.
Show hintHide hint
Consider how the load divides the current.
