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.
Learn about electric charge, a fundamental property of subatomic particles that determines their interaction with electric and magnetic fields. Explore the types, properties and methods of charging, such as friction, conduction and induction.
The electric field is an alteration of space caused by the presence of an electric charge. The electric field mediates the electric force between a source charge and a test charge. The electric field, like the electric force, obeys the superposition principle
In this chapter, we begin the study of the electric force, which acts on all objects with a property called charge. The electric force is much stronger than gravity (in most systems where both appear), but it can be a force of attraction or a force of repulsion, which leads to very different effects on objects.
The SI unit of electric charge is the coulomb (C), after the French physicist Charles Augustine de Coulomb (1736–1806). The most peculiar aspect of this new force is that it does not require physical contact between the two objects in order to cause an acceleration.
22 Νοε 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.
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.
