When the crystal current diode current is large, the bias is ___________
A. forward
B. inverse
C. poor
D. reverse
Answer: Option A
Solution(By Examveda Team)
In semiconductor diodes, the biasing conditions determine the direction of current flow. Let's analyze the options:Option A: Forward
- When the crystal current (diode current) is large, it typically indicates that the diode is under forward bias. In forward bias, the voltage applied to the diode allows a significant current to flow through it.
Option B: Inverse
- When the diode is under reverse bias, the crystal current should be very low or negligible. Reverse bias means that the voltage applied to the diode is in the opposite direction of its normal operation, and it prevents significant current flow.
Option C: Poor
- The term "poor" is not commonly used to describe the biasing condition of a diode. It doesn't convey a specific biasing state.
Option D: Reverse
- While a reverse bias condition does restrict current flow in a diode, it is not the condition associated with a large crystal current (diode current).
Therefore, the correct answer is Option A: Forward. When the crystal current (diode current) is large, the diode is typically under forward bias, allowing a significant current to flow through it.
