Question 1

What does Kirchhoff's Current Law state?

  • Total current in = Total current out
  • Current can be created
  • Current can be destroyed

πŸ’‘ Hint: Remember the concept of balance at nodes.

Question 2

True or False: The voltage gain of a common collector amplifier is typically less than 1.

  • True
  • False

πŸ’‘ Hint: Consider how the configuration and resistances affect gain.

Challenge Problems

Push your limits with challenges.

Question 1

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 = 100Ξ©. What is the expected gain?

πŸ’‘ Hint: Don't forget to account for voltage drops across load resistors.

Question 2

Analyze how changes in R_c to 500Ξ© affect the voltage gain in the same common collector amplifier. What do you expect in terms of output voltage change?

πŸ’‘ Hint: Focus on how each resistance influences overall circuit operation.
