What will be the resistance, Physics

Assignment Help:

Q The resistance of a platinum wire at 0oC is 4 Ω. What will be the resistance at 100oC, if the temperature coefficient of resistance is 0.0038/oC.

 Resistance at 100oC Rt = Ro (1+ αt)

                                                                = 4 (1 + (0.0038 × 100))

Rt = 5.52 Ω

Result: The resistance increases with the temperature.
