NEET Physics Resistivity MCQ Question
Two wires of equal length are made of two materials whose resistivities ρ₁ and ρ₂. They are connected in series. The equivalent resistivity of the combination is
ρ₁ + ρ₂ / 2
ρ₁ + ρ₂
2ρ₁ρ₂ / ρ₁ + ρ₂
ρ₁ρ₂ / ρ₁ + ρ₂
Correct Answer
Detailed Explanation
When resistors are connected in series, the equivalent resistivity is the average of the individual resistivities.
