Solution


Q.

Given below are two statements:                                       [2023]

Statement I: The equivalent resistance of resistors in a series combination is smaller than the least resistance used in the combination.

Statement II: The resistivity of the material is independent of temperature.

In the light of the above statements, choose the correct answer from the options given below:
1 Statement I is false but Statement II is true  
2 Both Statement I and Statement II are false  
3 Statement I is true but Statement II is false  
4 Both Statement I and Statement II are true  

Ans.

(2)

Req=R1+R2+R3 ⇒ St-1 False

Resistivity depends on temperature. ⇒ St-2 False
