[amp_mcq option1=”Source” option2=”Drain” option3=”Ground” option4=”Positive voltage rail” correct=”option4″]
The correct answer is: D. Positive voltage rail
A depletion-mode MOSFET is a type of MOSFET that is turned off when no voltage is applied to the gate. In order to turn it on, a positive voltage must be applied to the gate. This positive voltage will attract electrons from the source, which will create a channel between the source and drain. This channel will allow current to flow through the transistor.
The other options are incorrect because they will not turn on the depletion-mode MOSFET. Option A, source, is the terminal where the source electrode is connected. Option B, drain, is the terminal where the drain electrode is connected. Option C, ground, is the terminal that is connected to the ground.
I hope this explanation is helpful. Please let me know if you have any other questions.
