Statement I: Equivalent resistance of resistors in series is smaller than the least resistance in the combination.
Statement II: Resistivity of a material is independent of temperature. Choose the correct option.

Question

Statement I: Equivalent resistance of resistors in series is smaller than the least resistance in the combination.

Statement II: Resistivity of a material is independent of temperature. Choose the correct option.

G1 Physics · Accepted Answer

For series combination: Rₑq = R₁ + R₂ + ... Hence Rₑq is greater than each individual positive resistance. Statement I is false. Resistivity generally depends on temperature. Statement II is also false. Hence option B.
