In a field-effect transistor, what circuit parameter change causes the current to increase?
- AThe reverse bias is increased
- BA forward bias is applied
- CA forward bias is removed
- DThe reverse bias is decreased
Correct answer: D — The reverse bias is decreased. From the official ISED question bank, verified word for word.
Why
In a field-effect transistor, the gate acts like a valve that controls current flow. The full explanation — and one for every question — is in Pro.
