Answer 1

Answer:

1)The electrical potential difference is defined as the amount of work done to carrying a unit charge from one point to another in an electric field. In other words, the potential difference is defined as the difference in the electric potential of the two charged bodies.

2)Earth wire is used as a safety measure. Accidentally, if there is any leakage of current in an electrical appliances having metallic bodies, it is transferred to the earth through the earth wire and protects the user to get an electric shock.

3)Ohm's law, description of the relationship between current, voltage, and resistance. The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage, across the materials.

4)Conductivity vs Resistivity

Since conductivity is the measure of how easily electricity flows, electrical resistivity measures how much a material resists the flow of electricity.
