Question

When temperature of the metallic conductor increases its resistance
(A) increases
B) decreases
(C) remains constant
(D) first increases then decreases​

Answer 1

When temperature of the metallic conductor increases its resistance

(A) increases✔️✔️

B) decreases

(C) remains constant

(D) first increases then decreases

since kinetic energy of ions of the conducting wire increases due to gain of heat, they move rapidly in random directions, ( the positive ions), offering increased resistance.. ☑️☑️
