  1. Hall-effect
  2. Bipolar junction
  3. Field-effect ✔

Why: A field-effect transistor has gate, drain, and source electrodes. The gate controls current between the drain and source.

Huh, didn't know that: FET inputs can have very high impedance.

The dad joke
Why did the FET open the gate? The current wanted to get from the source to the drain.
