Physics · Series and parallel combinations of resistors, temperature dependence of resistance
When two same conducting rod are kept at different temperature,
When two same conducting rod are kept at different temperature,
- A. theirs resistivity will be different
- B. their resistivity will be same
- C. resistivity doesn't' depend on temperature
- D. none of the above
Step-by-step solution
Resistivity of a conductor depends on temperature, typically increasing with temperature for metals. Since the two identical rods are at different temperatures, their resistivities will be different.
