Translation guide
The ability of a component or circuit to store electric charge. In Japanese, this is almost always expressed with the technical term 静電容量 or the shorter 容量 in engineering contexts.
The physical property of a capacitor or conductor, measured in farads.
Referring to the idea of storing charge in everyday or educational contexts.
Descriptive phrase meaning 'ability to store electricity'. Used when explaining the concept to non-specialists.
コンデンサは電気を蓄える能力があります。
A capacitor has the ability to store electricity (capacitance).
In electronics, 容量 almost always means capacitance. However, in other fields (e.g., batteries, hard drives), it means capacity. If there's any risk of confusion, use 静電容量.
The standard technical term for capacitance in electronics and physics. Literally 'electrostatic capacity'.
このコンデンサの静電容量は10μFです。
The capacitance of this capacitor is 10 μF.
静電容量を測定する方法を教えてください。
Please tell me how to measure capacitance.
Short for 静電容量, commonly used in engineering when the context is clear. Can also mean 'capacity' in general, so context is important.
Outside of electronics, 容量 often means 'capacity' (e.g., storage capacity), so use 静電容量 to avoid ambiguity.
この回路の容量は十分ですか？
Is the capacitance of this circuit sufficient?
Loanword from English, used occasionally in technical documents but less common than 静電容量.
キャパシタンスの値が仕様と異なります。
The capacitance value differs from the specification.
Means 'the property called capacitance'. Useful when introducing the term.
静電容量という性質について学びました。
I learned about the property called capacitance.
