If X, Y and Z are the sizes of the emitter, base and collector of a transistor respectively, then
Show Hint
Transistor sizes: Collector>Emitter>Base.
Updated On: Jun 5, 2025
- X $>$ Z $>$ Y
- X $>$ Y $>$ Z
- Z $>$ X $>$ Y
- Z $>$ Y $>$ X
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In a transistor, the collector (Z) is the largest in size, followed by the emitter (X), and the base (Y) is the smallest. This size difference is crucial for the transistor's operation.
