Question

The conductivity of a conductor decrease, with temperature because on heating : (A) atoms vibrate vigorously (B) conductor expands (C) electrons gain energy (D) electrons vibrate vigorously

Tardigrade Admin · Accepted Answer

The random velocity of free electrons increases on heating as a result the rate of collisions increases and so the resistivity increases and conductivity decreases

Q. The conductivity of a conductor decrease, with temperature because on heating :

atoms vibrate vigorously

conductor expands

electrons gain energy

electrons vibrate vigorously

The random velocity of free electrons increases on heating as a result the rate of collisions increases and so the resistivity increases and conductivity decreases
