JEE Main 2023 — Current Electricity Question with Solution

JEE Main 2023 (15 Apr Shift 1)

Question

Given below are two statements:

Statement I : The equivalent resistance of resistors in a series combination is smaller than 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:

Correct answer
ABoth Statement I and Statement II are false

Step-by-step explanation

The formula for series equivalent resistance is given by 

Rs=R1+R2+......+Rn. 

Hence, the equivalent resistance will be the highest value compared to other resistances.

The resistivity of a material is given by,

ρ=ρ01+αΔT

Clearly, the resistivity is dependant on temperature.

Hence, this is the right option.
