Question

11) Assertion(A):-The drift velocity of electrons in a metallic wire will decrease if the temperature of the wire is
increased.
Reason(R):-On increasing temperature, conductivity of metallic wire decreases.
(a)Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c)A is true but R is false.
(d) A is false and R is also false.
12) Assertion A. D.​

Answer 1

Answer:

b. Both Assertion and reason are correct.

Explanation:

On increasing the temperature, resistivity increase which is the inverse of conductivity.
