Question

Two wires each made up of copper and nichrome have
equal lengths and equal resistance. Which is thicker? Tbe
resistivity of nichrome is greater than the resistivity of
copper. Why are alloys commonly used in electrical heating
devices such as electric toaster, electric iron etc.?​

Answer 1

Answer:

Resistivity of alloys is more than Resistivity of other metal and alloy does not burn easily

Answer 2

Answer:

alloy are used in electrical heating devices because it has higher resistivity
