Nichrome and copper wires of same length and same radius are connected

1.	Nichrome and copper wires of same length and same radius are connected in sereis. Current is `I` passed through them. Which up more ? Justify your answer.
Answer» In series combination, I is same for nichrome and copper . As rate heat product = P = ` I^(2)R` or ` P alpha R, , So, R _("nichrome")gt R _("copper")` for given length and diameters. Thus, nichrome will produce more heat.
