Electron conduction in an n-channel enhancement MOSFET is associated with:
- A p-channel enhancement
- B p-channel depletion
- C n-channel enhancement
- D q-channel depletion
Correct answer: C — n-channel enhancement. From the official ISED question bank, verified word for word.
Why
In an n-channel enhancement MOSFET, the device starts with no path for electrons to flow until a positive voltage is applied to the gate, which creates or "enhances" a conductive channel. The full explanation — and one for every question — is in Pro.
