Choose the right answer to the question. In a self-biased JFET circuit, if VD=VDD, then ID= from the following options along with the detailed explanation.
- Zero ampere
- Depend on Drain resistance
- Depends on Drain resistance and Gate current
- It cannot be determined
Answer – A.
A. In a self-biased JFET circuit, if VD=VDD, the drain current ID=0 Ampers.
Solution
In a self-biased JFET circuit, the detailed solution to the question is if VD=VDD, then ID= is provided here.
In a self-biased JFET circuit, after applying KVL to the Drain side, we get,
VD=VDD–IDRD
If we put VD=VDD in the above equation then,
∴ VDD=VDD–IDRD
∴ IDRD=0
∴ ID=0 Amperes.
Hence, Option (A) is the correct answer.
