47. Nichrome and copper wires of same length and same radius are connected in series. Current \( I \) is passed through them. Which wire gets heated up more? Justify your answer.(AI 2017)

Answer»
We know that,
    Heat, H=I²Rt

Hence, amount of Heating of the wire depends upon the Resistance of the Wire.
Now, we know that the resistance of Nichrome wire is much greater than that of the copper wire.
Hence, Nichrome wire gets more heated as compared to the Copper wire
