CBSE Class 10 Science 2020 · Paper 31/5/1 · Question 14
For question numbers 13 and 14, two statements are given – one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below.
Assertion (A): At high temperatures, metal wires have a greater chance of short circuiting.
Reason (R): Both resistance and resistivity of a material vary with temperature.
- (a)Both (A) and (R) are true and (R) is correct explanation of the assertion (A).
- (b)Both (A) and (R) are true, but (R) is not the correct explanation of the assertion (A).
- (c)(A) is true, but (R) is false.
- (d)(A) is false, but (R) is true.
