Fundamentally, electric charges are properties that possess an inherent ability to interact with one another. These effects give rise to electromagnetic fields. An EM field is a space around a charged particle where other charges experiencea push/pull. The strength of this interaction depends on the value of the charge and the separation between objects.
Electric fields can be visualized using lines of force, which show the course of the interaction that a positive charge would encounter at any given point in the field.
The concept of electric fields is fundamental to understanding a wide spectrum of physical phenomena, including {electricity, magnetism, optics, and even the Light electricity, class 10, chapter 12 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 caused by the relative position of electrically charged objects. This energy originates from the electrostatic forces {that exist between charged particles. Charges that are positive will attract charges that are negative, while like charges will repel each other. The potential energy in a system of charged objects depends on the magnitude and the distance.
Capability
Capacitance is the ability of a component to accumulate an charged charge. It is measured in farads, and it quantifies how much charge can be accumulated on a specific material for every volt applied across it.
Higher capacitance means the device can accumulate more charge at a given voltage, making it valuable in applications like filtering energy.

Resistance Law
Ohm's Law describes the relationship between in electronics. It states that the electric current through a conductor depends on the electromotive force applied across its ends and inversely proportional to its resistance. 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 design and analysis of electrical circuits..
