Q 11-10-058JEE MainJEE Main 2025 (29 Jan, Shift 2)Easy
A difference of temperature in a material can convert heat energy into electrical energy. To harvest the heat energy, the material should have
Answer: (D) low thermal conductivity and high electrical conductivity
A thermoelectric material works only while a temperature difference is kept across it.
- **Low thermal conductivity**, so heat does not simply leak through and wipe out the temperature difference.
- **High electrical conductivity**, so the generated current flows with little resistive loss.
