algebrat said:Potential blows up near charges (upside-down funnels glued together). There is a saddle point on the line segment between the charges (where the glue is), perhaps that was the point you were thinking of. If we are constrained to the line segment connecting the two charges, then there is a minimum in between, and it increases as you move closer to either of the charges.
curiousjoe94 said:I get it now. You say there's a minimum between the two charges, would it correct to assume this would never be zero?
Electric potential is a measure of the electric potential energy per unit charge at a given point in an electric field. It is also known as voltage and is measured in volts (V).
Electric potential is a scalar quantity that describes the energy of a charged particle at a given point, while electric field is a vector quantity that describes the force experienced by a charged particle at a given point.
The formula for electric potential is V = kq/r, where V is the electric potential, k is Coulomb's constant (9x10^9 Nm^2/C^2), q is the charge of the particle, and r is the distance from the particle to the point where potential is being measured.
Electric potential is typically measured using a voltmeter, which measures the potential difference between two points in an electric field. The unit of measurement is volts (V).
The factors that affect electric potential include the amount of charge present, the distance from the source of the electric field, and the medium in which the electric field exists. Additionally, the presence of other charges can also affect the electric potential at a given point.
