JEE Main 2024 Physics question
Two conductors have the same resistances at 0°C but their temperature coefficients of resistance are α₁ and α₂. The respective temperature coefficients for their series and parallel combinations are:
Answer: (C)
Solution
In series = 2R₀[1 + ((α₁ + α₂)/2)ΔT], so α_series = (α₁ + α₂)/2. In
