conservation of charge
A scientist demonstrates the conservation of charge with a simple electrostatics experiment.
Noun: * A fundamental principle in physics stating that the total electric charge within an isolated system remains constant over time. This means electric charge can neither be created nor destroyed; it can only be transferred from one object to another or converted between different forms (e.g., when a particle and its antiparticle annihilate, their net charge remains zero).
The term is used primarily in scientific contexts, especially in physics and chemistry, to describe an inviolable law of nature. * It is often stated as a law or principle. * It applies to isolated systems, meaning systems that do not exchange charge with their surroundings.
- In any chemical reaction, conservation of charge is always obeyed; the total charge on the reactants equals the total charge on the products.
- The conservation of charge explains why when you rub a balloon on your hair, the balloon gains a negative charge and your hair gains an equal positive charge.
- Physicists verified the conservation of charge in particle accelerator experiments involving the creation and destruction of matter.
- Linked to Gauge Symmetry: In theoretical physics, conservation of charge is a consequence of a fundamental symmetry of the universe known as .
- Local Conservation: The principle implies a , meaning charge cannot simply vanish in one place and appear in another without a current flowing between them, as described by the continuity equation.
- Charge Conservation: A synonymous phrase often used interchangeably.
- Conservation Law: The general class of physical laws to which conservation of charge belongs, including conservation of energy and momentum.
- Conserved Quantity: A property, like electric charge, that remains constant in an isolated system.
- Charge conservation
- Principle of charge conservation
- Electric Charge: The physical property that is conserved.
- Continuity Equation: The mathematical expression describing the local conservation of charge.
- Noether's Theorem: A fundamental theorem linking conservation laws to symmetries in physics, under which conservation of charge falls.
