Question

The PN junction can be named as:
1. Triode
2. Tetrode
3. Pentode
4. Diode

Answer 1

Correct Answer - Option 4 : Diode

P-N Junction:

• A p-n junction is a boundary between two semiconductor material types, namely the p-type material and the n-type material, inside a semiconductor.
• The p-side of material has holes as majority carrier and electron as minority carrier.
• The n-side of material has electrons as majority carrier and holes as minority carrier.
• In a semiconductor, the p-n junction is created by the method of doping and fabrication.

 

Diode:

• Di means two and Ode means electrode, hence we can say Diode has two electrodes.
• In the p-n junction, there is two-electrode one is positive and the other is negative.
• Hence, the p-n junction is named the p-n junction diode.
