Explanation:

A.) power=current times voltage so

power 100w and 150W

voltage 220V

so current is voltage divided by power which is

current is 2.2amps and 1.5amps

Now resistance is voltage divided by current so

100 ohm and 147 ohm.

B.) 1KWH is 1000W so

1000W is 30p

100W would be 3p and

150W would be 4.5p
