- Charge Electrons are negatively charged particles and they transfer electrical energy from a cell, through conducting wires, as an electric current. Charge is measured in coulombs, C. The charge of an electron is 1.6 x 10 -19 C. In other words, it takes 6,250,000,000,000,000,000 electrons to make up 1 coulomb of charge.

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
Learn what electric charge is, how it is measured, and what types and properties it has. Find out how charge is transferred by friction, conduction, and induction, and how Coulomb's Law describes the force between charges.

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.
Learn about the history, properties and types of electric charge, and how it is transferred and measured. Explore the triboelectric series, the amber effect, and Franklin's experiments with lightning and kites.
In physics, a charge is any of many different quantities, such as the electric charge in electromagnetism or the color charge in quantum chromodynamics. Charges correspond to the time-invariant generators of a symmetry group, and specifically, to the generators that commute with the Hamiltonian.
