Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
Calculate the base current (IB) for a fixed bias circuit where VCC = 15V, VBE = 0.7V and RB = 1MΩ.
💡 Hint: Use the formula IB = (VCC - VBE) / RB.
Question 2
Easy
What is the main disadvantage of using fixed bias for transistor amplifiers?
💡 Hint: Consider how changes in transistor characteristics affect the Q-point.
