Definition
- Noun:
- A physical property of matter that causes it to experience a force when placed in an electromagnetic field: Electric charge is a fundamental property of subatomic particles, such as protons (positive charge) and electrons (negative charge). It is quantized and conserved.
- The quantity of unbalanced electricity in a body: This refers to the net amount of charge, construed as an excess or deficiency of electrons, resulting in either a positive or negative charge.
Usage Examples
- Noun:
- The electric charge of a proton is positive.
- Rubbing the balloon on wool gave it a static electric charge.
- The capacitor stores a significant electric charge.
Advanced Usage
- "To hold an electric charge": To retain a net quantity of charge.
- A Leyden jar can hold a large electric charge.
- "Distribution of electric charge": The manner in which charge is arranged in or on an object.
- The distribution of electric charge on the conductor's surface is uniform.
Variants and Related Words
- Charge (n): Often used as a shorter form of "electric charge" in physics contexts.
- The total charge in the system is constant.
- Charged (adj): Having a net electric charge.
- The rod became charged after contact with the fur.
- Electrostatics (n): The branch of physics that studies stationary electric charges.
Synonyms
- Charge (in physics contexts)
- Electrostatic charge
Related Phrases
- Unit of electric charge: The coulomb (C) is the standard SI unit.
- One coulomb is a very large amount of electric charge.
- Conservation of electric charge: A fundamental law stating that the total electric charge in an isolated system never changes.
- The experiment demonstrated the conservation of electric charge.
Noun
