In the CBSE curriculum, understanding the concept of electric charge and its various types is of utmost importance.
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

1 day ago · What is charge? In GCSE physics, charge is a property that particles have if they experience a force when placed in an electric field. Charge can be positive or negative. For example, electrons are negatively charged particles, and protons are positively charged particles. Oppositely charged particles are attracted to one another, and like ...
Sep 26, 2024 · Electric charge, basic property of matter carried by some elementary particles that governs how the particles are affected by an electric or magnetic field . Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed.

Apr 14, 2019 · In the context of chemistry and physics, charge usually refers to electric charge, which is a conserved property of certain subatomic particles that determines their electromagnetic interaction. Charge is a physical property that causes matter to experience a force within an electromagnetic field.
- Anne Marie Helmenstine, Ph.D.
Electric charge (symbol q, sometimes Q) is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge can be positive or negative. Like charges repel each other and unlike charges attract each other. An object with no net charge is referred to as electrically neutral.
The property of matter that is responsible for electrical phenomena is called charge. The amount of positive and negative charge in most things is balanced.
