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:

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,
$ρ = ρ^{0} (1 + α Δ T)$
Clearly, the resistivity is dependant on temperature.
Hence, this is the right option.
