Question

temperature coefficient of resistance is 0.00125 per "C. Resistance at 300°K is 1 ohm.
What will be the temperature in (K) when resistance becomes 2 ohm?​

Answer 1

Hii I will help you ✌️

=> per^∘C. At 300K, its resistance is 1 ohm. This resistance of the wire will be 2 ohm at. T2=854∘C=1127K.
