Question

Two identical wires one of nichrome and other of copper are connected in series and a current

(I) is passed through them. State the change observed in the temperature of the two wire.

Justify your answer. State the law which explain the above observation​

Answer 1

Nichrome and copper wires of the samelength and radius areconnected in a series. A current, I, is passed through them. ... Therefore resistance of Nichrome wire will be more than that ofCopper. Since more resistance means more I^2R loss (which is dissipated as heat).
