T6B05
What type of transistor has a gate, drain, and source?
- A.Varistor
- B.Field-effect (correct answer)
- C.Hall-effect
- D.Bipolar junction
WhyA field-effect transistor has a gate, drain, and source. A field-effect transistor is defined by its three terminals: gate, drain, and source, answer B. A varistor (A) is a two-terminal voltage-dependent resistor, a Hall-effect device (C) senses magnetic fields rather than switching current, and a bipolar junction transistor (D) instead uses emitter, base, and collector terminals.
