Let%27s explore the three terminals of a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) in detail:

1. Gate (G):
- The gate terminal is where external voltage is applied to control the MOSFET%27s behavior.
- By varying the gate-source voltage (V_GS), we influence the flow of current between the drain and source.
- The gate voltage determines whether the MOSFET is in the ON or OFF state.
- It acts as a voltage-controlled device.

2. Drain (D):
- The drain terminal is where the current flows out of the MOSFET.
- When the MOSFET is conducting, current moves from the drain to the source.
- In amplifiers and switching circuits, the drain is a crucial connection.

3. Source (S):
- The source terminal is where the current enters the MOSFET.
- It serves as the reference point for the drain current.
- The voltage between the source and the gate (V_GS) controls the channel conductivity.

In summary, the MOSFET%27s three terminals—gate, drain, and source—play essential roles in regulating current flow and determining its behavior in electronic circuits¹²³⁴⁵.
