Potential difference is measured in units called

The correct answer is volt.

Step-by-step explanation:

Potential difference is the work done in bringing the charge from one point to another.

Or

Potential difference between the two points is defined as the change in the potential energy when the charge is moved from one point to other point.

The expression for the potential difference in terms of  work done and charge is as follows;

Here, is the change in the potential difference, W is the work done and q is the charge.

The SI unit of potential difference is volt.

1 volt is defined as the one joule of work done in bringing one coulomb charge from one point to another.

Therefore, potential difference is measured in units called volt.

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
