Technician exam question T6B09
Subelement T6, ELECTRONIC AND ELECTRICAL COMPONENTS· Group T6B
What are the names for the electrodes of a diode?
- A.Plus and minus
- B.Source and drain
- C.Anode and cathode (correct answer)
- D.Gate and base
WhyAnode and cathode are the names for the electrodes of a diode. A diode's two electrodes are called the anode and cathode, terms that describe which end current enters and exits during forward conduction, answer C. Plus and minus (A) describe battery terminals, not diode electrodes, source and drain (B) belong to a field-effect transistor, and gate and base (D) mix terminals from two different transistor types, neither of which is a diode.
