Point Charge

A point charge is an idealized concept in physics representing a particle with an electric charge that occupies no physical space, meaning its size is considered negligible. It creates an electric field around it, influencing other charges nearby. This simplification helps in understanding and calculating electric forces and fields without dealing with complex shapes or sizes. Point charges are useful in physics models because they focus on the fundamental behavior of charges, making complex problems more manageable by treating charges as single points with specified amounts of electric charge.
