Fundamentally, electric charges are properties that possess an inherent tendency to interact with one another. These forces give rise to electromagnetic fields. An EM field is a space around a object where other charges experiencea force. The here strength of this influence depends on the size of the charge and the distance between objects.
Electric fields can be visualized using field lines, which show the course of the influence that a test charge would feel at any given point in space.
The concept of electric fields is fundamental to understanding a wide variety of physical phenomena, including {electricity, magnetism, optics, and even the structure of atoms.
Coulomb's Law
Coulomb's Law is a fundamental/pivotal/essential principle in physics that quantifies the attractive/repulsive/interacting force between two electrically charged/charged/polarized objects. This law/principle/equation states that the magnitude of this force is directly proportional/linearly dependent/intimately related to the product of the magnitudes of the charges and inversely proportional/reverses with the square of/dependent on the reciprocal square of the distance between their centers. Mathematically, it can be expressed as F = k * (|q1| * |q2|) / r^2, where F is the force, q1 and q2 are the magnitudes of the charges, r is the separation/distance/span between them, and k is Coulomb's constant.

- Conversely/On the other hand/In contrast, a larger distance between the charges weakens/decreases/reduces the force.
Potential Energy
Electric potential energy represents stored energy generated from the relative position of electrically charged objects. This energy originates from the attractions {that exist between charged particles. An object with a positive charge will attract a negative charge, while identical charges repel. The potential energy among charged particles is determined by the size the separation between them.
Capactiance
Capacitance is the ability of a system to store an charged charge. It is measured in coulombs, and it quantifies how much charge can be stored on a particular conductor for every potential difference applied across it.
Higher capacitance means the conductor can store more charge at a given voltage, making it valuable in applications like filtering current.

Voltage-Current Relationship
Ohm's Law is a fundamental principle in electrical circuits. It indicates the current through a conductor is directly proportional the potential difference applied across its ends and inversely proportional to its inherent property. This {relationship can beexpressed as an equation: V = I*R, where V represents voltage, I represents current, and R represents resistance. This law is essential for understanding the operation of power systems..
