Question

whats the relationship between the resistivity of an electric cable and the temperature?

Answer 1

Resistivity will b constant for all temperature

Answer 2

thanks:)

Answer 3

Resistance will increase with increasing temperatire

Answer 4

Welcome

Answer 5

how come?

Answer 6

It's directly proportional to its temperature.

Answer 7

in electric wires flow of electrons as flow of water in a pipe.when temperature increases electrons flow in wire also increases but while flowing electrons collide with atoms of the wire.hence its flow decreases.current flow decreases.resistivity is different from resistance . resistance per unit length of unit are is called resistivity. is constant for specific substances.
