In a field-effect transistor, which two electrodes are connected to the ends of the channel?
- AGate and drain
- BSource and base
- CSource and drain
- DSource and gate
Correct answer: C — Source and drain. From the official ISED question bank, verified word for word.
Why
In a field-effect transistor, the channel is the path where electricity flows, and this path runs directly between the source, where carriers enter, and the drain, where they exit. The full explanation — and one for every question — is in Pro.
