7.4: Calculations of Electric Potential - Physics LibreTexts
Find the electric potential of a uniformly charged, nonconducting wire with linear density \(\lambda\) (coulomb/meter) and length L at a point that lies on a line that divides the wire into two equal parts.
Electric potential - Wikipedia
In short, an electric potential is the electric potential energy per unit charge. This value can be calculated in either a static (time-invariant) or a dynamic (time-varying) electric field at a specific time with the unit joules per coulomb (J⋅C −1 ) or volt (V).
Electric Potential - Definition, Formula, SI Unit - GeeksforGeeks
2024年5月3日 · The formula for electric potential at a point in an electric field, denoted as V, is: V = \frac {k \cdot Q} {r} V = rk⋅Q . Where: V represents the electric potential at the point, k is Coulomb's constant (a proportionality constant), Q is the magnitude of the point charge creating the electric field, and.
