Question

What is the slope of the output load line characteristics for the circuit shown in the below Figure? 

• A. \(-\frac{1}{R_C}\)
• B. \(-\frac{1}{R_C + R_B}\)
• C. \(-\frac{1}{R_B}\)
• D. \(-\frac{1}{R_C + R_B}\)

Hint:

The slope of the load line in a transistor circuit is related to the load resistance and is crucial for analyzing transistor behavior.

Answer 1

The Correct Option is A

The output load line is the relationship between the collector current \(I_C\) and collector-emitter voltage \(V_{CE}\) in a transistor amplifier. The slope of this line is determined by the load resistance, which is the resistance in the collector, i.e., \(R_C\). Therefore, the slope is \(-\frac{1}{R_C}\), indicating the inverse relationship between the collector voltage and current.
Conclusion: The correct slope of the load line is \(-\frac{1}{R_C}\).
