1.

Give Scientific reasons . In the electric equipment producing heat e.g. iron, electric heater, boiler, toaster, etc, an alloy such as Nichrome is used, not pure metals.

Answer»

Solution :1.Electric equipments producing HEAT MAKE use of heating EFFECT of electric current.
2. Electrical conductors having HIGHER RESISTIVITY are used here.
3. Nichrome is an alloy and therefore it has a higher resistivity than pure metals.
4. Hence, nichrome is used to get higher amount of heat.
