6 sample questions

Question 1.
State Kirchhoff’s Current Law (KCL) and describe its significance in electronic circuits.
Show hintHide hint
Think about how currents flow and balance in a junction.
Question 2.
Define input resistance and discuss its importance.
Show hintHide hint
Consider how the amplifier interacts with the signal source.
3Question 3.
What does Kirchhoff's Current Law state?
- Total current in = Total current out
- Current can be created
- Current can be destroyed
Show hintHide hint
Remember the concept of balance at nodes.
4Question 4.
True or False: The voltage gain of a common collector amplifier is typically less than 1.
- True
- False
Show hintHide hint
Consider how the configuration and resistances affect gain.
Question 5.
You have a common collector amplifier where input voltage is applied, and the collector is loaded with a resistance R_c. Calculate v_out when the load draws a current of 10mA, given that input voltage is 1V and R_c = 100Ω. What is the expected gain?
Show hintHide hint
Don't forget to account for voltage drops across load resistors.
Question 6.
Analyze how changes in R_c to 500Ω affect the voltage gain in the same common collector amplifier. What do you expect in terms of output voltage change?
Show hintHide hint
Focus on how each resistance influences overall circuit operation.
