- Any electric charge placed on a conductor or within the dielectric or the freely moving charge can be termed a free charge. The opposite of a free charge is known as a polarisation charge or a bound charge. This kind of change is visible when electrons are tightly knit to the nucleus and cannot move freely.

Coloumb is the unit of electric charge. Mathematically, the definition of a coloumb is represented as: In the equation, Q is the electric charge, I is the electric current and t is the time.
Electric charge possesses several important properties that help us understand its behaviour. Let’s explore these properties:
We know that like charges repel each other, while unlike charges attract. However, have you ever wondered about the strength of these forces acting between charges? Coulomb’s Law offers us a method to calculate this force precisely. The Coulomb’s Law is given by the expression: By applying Coulomb’s Law, we can quantitatively determine the strength...
The process of supplying electric charge to an object or causing it to lose electric charge is referred to as charging. There are three distinct methods by which an initially uncharged object can acquire charge: 1. Charging by friction ( triboelectric charging) 2. Charging by conduction 3. Charging by induction

Key Terms. Key Equations. Summary. 5.2 Electric Charge. There are only two types of charge, which we call positive and negative. Like charges repel, unlike charges attract, and the force between charges decreases with the square of the distance.
19.1. Note that we assigned a positive charge to the charges in Figure 19.3. Normally, negative charges—electrons—are the mobile charge in wires, as indicated in Figure 19.2. Positive charges are normally stuck in place in solids and cannot move freely.
No free particle can have less charge than this, and, therefore, the charge on any object—the charge on all objects—must be an integer multiple of this amount. All macroscopic, charged objects have charge because electrons have either been added or taken away from them, resulting in a net charge.
Key terms. What unit is “A”? How to calculate net charge. There are two kinds of electric charge, positive and negative. On the atomic level, protons are positively charged and electrons are negatively charged. Is this true for all particles?
