Answer to Question #307644 in Electric Circuits for Boo

Question

Describe in a creative way the effect of temperature increases on the resistance of a metallic conductor. Also, describe the ability of the material to conduct current in terms of its resistivity and conductivity.

Note: You may express your answer through a drawing, just by making a slogan or a poster. It is all up to you as long as you can describe

Answer 1

Answer

According to physics, When the temperature of metallic conductor increases, the velocity of free electrons increases but it also cause increase in amplitude of vibration of metallic atoms which cause some extra resistance in the path of free electron. Hence resistance increases with increase in the temperature.
