Question

1 ) List the factors on which the resistance of a
conductor in the shape of a wire depends.
2) Why are metals good conductors of electricity
whereas glass is a bad conductor of electricity?
Give reason.
3) Why are alloys commonly used in electrical
heating devices? Give reason.​

Answer 1

Explanation:

alloys commonly used in electrical heating devices power was too fast

Answer 2

Answer:

a) length of the conductor

material of the wire

area of cross section

b) metals are the good conductor of electricityas the have large volume of free electrons.

c) alloys have high melting as compare to other matals. They are made up of homogenous mixture of metals or metals and non metals
