Challenge Problems

Push your limits with challenges.

Question 1

Given a common base amplifier with an input voltage of 2V and an observed output voltage of 20V, derive the voltage gain and discuss how input resistance affects this relationship.

💡 Hint: Ensure to consider the impact of source resistance on actual voltages.

Question 2

Analyze a scenario where the input resistance is significantly lower than the load resistance; what changes occur in signal propagation between input and output?

💡 Hint: Consider how voltage drops across resistances affect output.
