Question

when temperature of a junction diode increases then how its resistivity change​

Answer 1

Increase in temperature in a junction diode increases the resistivity of the conductor.

Explanation:

• When temperature is increased in a P-N junction diode then its conductivity increases and current also increases due to more flow of electrons between the holes.
• The increase in temperature decreases the barrier potential and allow the electron flow between the holes thus generating more conductance.
• By keeping the voltage constant the increase in temperature increases the current but the resistance also increases.
