Why are alloys commonly used in electrical heating devices? Give reason.

i] Heating elements of electrical heating devices is made up of an alloy rather than a pure metal. Give two reasons. ii] Four resistors of 2Omega each are joined end to end to form a square. Calculate the equivalent resistance of the combination between two adjacent corners?

Assertion (A): Alloys are commonly used in electrical heating devices like electric iron and heater. Reason (R): Resistivity of an alloy is generally higher than that of its constituent metals but the alloys have low melting points then their constituent metals.
