A field-effect transistor (FET) regulates current flow through a semiconductor channel using an electrostatic field. Which terminal receives the controlling input voltage to modulate this current?

  1. A
    Drain
  2. GateCevap
  3. C
    Source
  4. D
    Cathode

Cevap

The gate terminal is the input control electrode of a field-effect transistor that receives voltage to regulate channel current.
In a field-effect transistor (FET), the gate terminal functions as the control element. An applied input voltage at the gate generates an electrostatic field that modulates the resistance and carrier flow through the channel connecting the source and drain.

Adım Adım Çözüm

1
Identify the standard three terminals of a field-effect transistor (FET).
A field-effect transistor consists of the source, drain, and gate terminals.
Identifying the terminal designations is the first step in determining their functional roles.
2
Differentiate between the current-carrying terminals and the control terminal.
Current travels through the channel between the source and drain terminals, while voltage applied to the gate terminal establishes an electric field that widens or restricts the channel.
The gate provides voltage-based control over current conduction without requiring significant input current.
