Answer:

hii your answer is as follows:

Explanation:

Ohm's Law states that the potential difference between two points is directly proportional to the electric current 1 ohm (Ω) of Resistance (R) is equal to the flow of 1 A of current through a conductor between two points having potential difference equal to 1 V.

the wire used in an electric heater is very thick , because if the wire is thick it offers less resistance therefore allowing more current to pass through it thereby increasing the heat caused in heater to boil the water fast

whereas in fuse wire is very thin and when more than the rated current passes through it the fuse wire melts and protects the other electrical appliances from getting damaged.

series arrangements are not used for domestic circuits because:

a) In series arrangement same current will flow through all the appliances, which is not required

b) Total resistance of domestic circuit will be sum of the resistance of all appliances and hence current drawn by the circuit will be less.

c) We cannot use independent on/off switches with individual appliances.

Mark as brainliest if you are satisfied with my answer

Answer:

a . the potential difference across the two points of a current carrying conducted is directly proportional to the current though the conductor and provided it's temperature remains constant.

b. wire used in heater has high melting point while the wire used in fuse has low melting point.

c. series arrangement is not used because;

- if one material fail current will doesn't pass to next equipment.
