$<body bgcolor=blue><marquee direction="up"><font color=red blue>$ At some instant time and current are constants. then heat is directly proportional to resistance. The current is contant because the coil which produce heat can be consider as series connected as resistors. Hence,we need high resistance in heaters.

Answer:

Nichrome wire should be used as the heating element in an electric iron. The reasons are mentioned below: • High resistivity thus ensuring the wires to heat up faster. • High melting point which does not melt the wire with thedue to an increase in temperature
