Show hintHide hint
Think about the function of the amplifier in your audio systems.
Question 2.
What role does a BJT play in current amplifiers?
Show hintHide hint
Consider which electronics components are essential in amplifying signals.
3Question 3.
What does a current amplifier primarily do?
- Amplifies voltage signals
- Amplifies current signals
- Both
Show hintHide hint
Recall the functionality of current versus voltage amplifiers.
4Question 4.
True or False: An AC coupling capacitor allows DC signals to pass.
- True
- False
Show hintHide hint
Think about how coupling capacitors are used in circuits.
Question 5.
You have a BJT current amplifier with an unloaded current gain of 10. If the input current is 2 mA, what is the output current?
Show hintHide hint
Simply multiply the input by the gain.
Question 6.
Explain how to account for loading effects when connecting a load resistor to the output of a current amplifier.
Show hintHide hint
Think back to the formulas we derived for loading effects.
