Physics Current Electricity JEE Main 2023 MCQ (Single Correct)

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:

Both Statement I and Statement II are false

Both Statement I and Statement II are true

Statement I is true but Statement II is false

Statement I is false but Statement II is true

Text Solution

Verified by Experts

The correct answer is:

The formula for series equivalent resistance is given by

R s = R 1 + R 2 +......+R n

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

The resistivity of a material is given by,

Clearly, the resistivity is dependent on temperature.

Hence, this is the right option.
