Electric potential –Electric potential at any point is the work done in bringing a unit positive charge in an electric point to that point. from the center of the disc.
What is the potential due to uniformly charged disc?
for the charged disc, that the electric potential is smallest near the disc and the magnitude of the electric field is maximum near the center.
Is electric potential zero when electric field is zero?
Yes, electric potential can be zero at a point even when the electric field is not zero at that point. Considering the case of the electric dipole will help us understand this concept.
Where is the potential due to a line charge zero?
The total potential at the point will be the algebraic sum of the individual potentials created by each charge. If you place the -1 C charge 1 cm away from the point then the potential will be zero there.
How is potential difference calculated?
V=Uq. The electric potential difference between points A and B, VB−VA is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta.
