Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the typical voltage gain of a common base amplifier?
💡 Hint: Think about how voltage gain is expressed as an output over input ratio.
Question 2
Easy
What is the input impedance for the common base amplifier?
💡 Hint: Remember, low impedance means the amplifier draws more current.
