A type of metals containing alloys, ceramics etc., when heated their temperature reaches to a state called Transition temperature state and their resistance reaches to zero. These types of metals are called
Correct answer: D. Superconductors
- A. Conductors
- B. Insulators
- C. Semi-conductors
- D. Superconductors
Explanation
Superconductors are materials that exhibit zero electrical resistance below a certain critical temperature. This means that electricity can flow through them without any loss of energy. This phenomenon is called superconductivity.

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.
