Silicon is the most commonly used:
Correct answer: B. Semi-conductor
- A. Insulator
- B. Semi-conductor
- C. Dielectric
- D. Conductor
Explanation
Silicon, a very common element, is used as the raw material of semiconductors because of its stable structure.Silicon is also less expensive as compared to other elements that may be suitable to make semi conductors. Being a semiconductor, the element is put into use for making transistors. Silicon is widely used in computer chips and solar cells. It is a vital component of Portland cement. Silicon is used in the production of fire bricks.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
