The highest energy level is completely filled in an _.
Correct answer: A. Insulator
- A. Insulator
- B. Semi-conductor
- C. Conductors
- D. None of these
Explanation
Insulators are materials that don't conduct electricity well because their electrons are tightly bound and don't move easily. The highest energy level is filled therefore electrons cannot jump to higher energy levels.

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.
