Combination of Resistors

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:

Show answer and solution

Answer: (c)

Statement I: in series $R_{eq} = R_1 + R_2 + \dots$ , which is larger than the largest resistor, so I is false.
Statement II: resistivity changes with temperature, $\rho = \rho_0(1 + \alpha\Delta T)$ , so II is false.
So the answer is (c) both statements are false.
