Question

relation between resistance temperature area of cross section and length​

Answer 1

Resistance an length are directly proportional

That is if length of a conductor increases, its resistance increases and vice versa

Resistance and area of cross section are inversely proportional

That is if area of cross section of a conductor increases, its resistance decreases and vice versa

Resistance and temperature are directly proportional

That is if temperature of a conductor increases, its resistance increases and vice versa

Hope it helped :)
