Insulating channel
Conducting channel
Vdd
Vss
Answer is Right!
Answer is Wrong!
The correct answer is: A. Insulating channel
In depletion mode, the channel between the source and drain is depleted of charge carriers, which makes it an insulator. This means that there is a high resistance between the source and drain, and no current will flow unless a voltage is applied.
The other options are incorrect because:
- Option B: A conducting channel would allow current to flow between the source and drain, even without a voltage applied.
- Option C: Vdd is the positive supply voltage, and Vss is the negative supply voltage. Neither of these voltages would cause current to flow between the source and drain in depletion mode.
- Option D: This is not a valid option.
