The output characteristics of a transistor in CE mode is the graph obtained by plotting
Show Hint
Output characteristics show the output current against the output voltage while the input current is held fixed.

- \(I_{C}\) against \(I_{B}\) at constant \(V_{BE}\)
- \(I_{C}\) against \(V_{EB}\) at constant \(V_{CE}\)
- \(I_{C}\) against \(I_{B}\) at constant \(V_{CE}\)
- \(I_{C}\) against \(V_{CE}\) at constant \(I_{B}\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
In CE mode the input is applied between base and emitter and the output is taken between collector and emitter.
Step 2: Output characteristics
They show how the output current \(I_{C}\) changes with the output voltage \(V_{CE}\) while the input current \(I_{B}\) is kept constant.
Step 3: Compare the options
Plots of \(I_{C}\) against \(I_{B}\) are transfer characteristics, and plots involving \(V_{BE}\) concern the input side.
Final Answer:
The output characteristic is a graph of I C against V CE at constant I B. \[ \boxed{\text{(D) }I_{C}\text{ against }V_{CE}\text{ at constant }I_{B}} \]
