Question

Let \(i_e\), \(i_c\), and \(i_b\) represent the emitter current, the collector current, and the base current respectively in a transistor then

• A. \( i_c \) is slightly smaller than \( i_e \)
• B. \( i_c \) is slightly greater than \( i_e \)
• C. \( i_b \) is much greater than \( i_c \)
• D. \( i_b \) is much greater than \( i_e \)

Hint:

In a transistor, the emitter current is the largest, and the collector current is slightly smaller than the emitter current.

Answer 1

The Correct Option is A

Step 1: Current Relationships in a Transistor.
In a transistor, the emitter current \( i_e \) is the sum of the collector current \( i_c \) and the base current \( i_b \). Hence, the collector current \( i_c \) is slightly smaller than the emitter current \( i_e \) due to the small fraction of current that goes into the base.

Step 2: Conclusion.
The correct answer is ( \( i_c \) is slightly smaller than \( i_e \).
