Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the input resistance in a CE amplifier with a base resistance of 1 kΩ and emitter resistance of 1.3 kΩ?
💡 Hint: Use 1/(1/R_B + 1/r_π) for parallel resistance.
Question 2
Easy
Define output resistance in common emitter amplifiers.
💡 Hint: Think about what influences the current delivery at the output.
