Question

electric potential and potential difference?

Answer 1

The amount of work done required to bring one coulomb charge from one point to another point in an electric field is known as potential difference.The potential difference sets charges in in motion in the conductor and produce electric current.
Eqn: W=V/Q
SI unit : volt

Answer 2

Electric potential: Electric potential at a point P is equal to the change in electric potential energy per unit test charge when it is moved from a reference pointto the point P. It can also be defined as the work done per unit test charge from the reference point to the point P (provided the kinetic energy of the test charge is not changed).
V = kQ / r Unit is Nm/C Electric potential is used mostly in the study of electrostatics.Potential difference: Potential difference between two points is defined as the amount of work done in moving a unit positive charge from one point to another
.Potential difference between twopoints is also equal to the productof the electric field and the distance between the two points.
V = E.dIt is measured in Voltage or simply volt (V).Potential difference is mostly used in the study of current electricity.Both electric potential and potential difference can be expressed in V and Nm/C.
