1.
electric charge; electrical charge
A fundamental property of matter that causes it to experience electromagnetic force. Comes in positive and negative forms, with interactions between charges producing electricity, magnetism, and electromagnetic radiation.
電子は負の電荷を持つ。
Electrons carry a negative charge.
同じ電荷どうしは反発する。
Like charges repel each other.
静電気は物体の表面に電荷がたまることで発生する。
Static electricity occurs when electric charge accumulates on the surface of an object.
Compound of 電 ('electricity') and 荷 ('load; cargo; charge'). The fundamental physics term for the quantity of electricity carried by a particle or body. Encountered in high school physics education and technical contexts.
USAGE:
- A core concept in physics: 正の電荷 ('positive charge') and 負の電荷 ('negative charge').
- The SI unit of electric charge is the coulomb (クーロン).
- Also used in chemistry when discussing ions: an ion is an atom that has gained or lost 電荷.
COMMON COLLOCATIONS:
- 正の電荷: positive charge
- 負の電荷: negative charge
- 電荷を帯びる: to carry a charge; to become charged
- 電荷の保存: conservation of charge
SIMILAR WORDS:
- 電流: electric current — the flow of electric charge through a conductor
- 電圧: voltage — the difference in electric potential that drives current
- 静電気: static electricity — stationary electric charge on a surface
- 帯電: electrification; becoming charged — the process of acquiring an electric charge
