Electric potentials

Topic

The concept of electric potential is a fundamental aspect of electromagnetism, serving as a measure of potential energy per unit charge at a specific point in an electric field. It provides a convenient way to describe the potential energy landscape shaped by electric charges. Electric potential is particularly useful because it allows the determination of the electrical potential energy for a charge at various positions without having to calculate the work done against the electric field. In essence, electric potential quantifies how much work would be needed to move a charge from one point to another within an electric field. A higher potential means that a charge at that point has more potential energy; moving a charge to a point of higher potential requires work, while moving it to a lower potential releases energy.
