Question

Define electric potential difference. Distinguish between electric potential difference and electric potential.

Answer 1

Answer:

First case is related to Electrical potential.

Suppose A source charge you can say a power full charge is placed so it has some influence space around it where it can affect other charges around it. So if we have to bring one point charge which is placed outside influence area suppose placed at infinity, to inside influence space of source charge some work has to be done and that work is restored as a potential of that charge that potential is known as electric potential.

Case 2 - this case refers to potential difference

In this case test charge is already placed inside influence area of source charge so it already got some amount of electric potential if test charge move between two point with in influence of source charge there will be differences in the potential across those two points so this is called potential difference.

Electric Potential =Work done/q

Where work is done to bring a charge q from infinty to any point inside influence space of Q

Potential Difference = WORK DONE/ q

Where work is done to bring a charge q between two points within influence space of Q.

I hope that you will be able to understand the difference.

Thank you

Answer 2

Answer:

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