这个电容器的电容量以法拉为单位测量。
You can increase the capacitance by bringing the plates closer together.
你可以通过将极板靠得更近来增加电容。
The circuit has high capacitance, so it can store a large charge.
这个电路具有高电容,因此能储存大量电荷。
电容通常作不可数名词,表示某器件或材料的电容时用 the capacitance of 后接该器件或材料。
The capacitance of the capacitor is measured in farads.
该电容器的电容用法拉来衡量。
要说明具体电容数值时,常用 have a capacitance of 后接数字和单位。

Not this
I bought a capacitance for the radio.
Use this
I bought a capacitor for the radio.
汉语的“电容”既可以指电容这一物理量,也可以指电容器元件;英语中capacitance只表示储存电荷的能力/电容值,指元件必须用capacitor。此处要表达“买一个元件”,所以应改为capacitor。
Not this
This battery has a large capacitance.
Use this
This battery has a large capacity.
capacity表示容量或电量,capacitance专指电容器储存电荷的电容。电池的储电能力用capacity,不能用capacitance;两词拼写相近但含义不同,改正后保留了“电池容量大”的意思。
Focus on the distinctions below. Other candidates are kept compact until a reliable usage note is available.
杂散电容
Stray capacitance can affect the performance of high-frequency circuits.
杂散电容会影响高频电路的性能。
寄生电容
Engineers try to minimize parasitic capacitance in the layout.
工程师们尽量减小布局中的寄生电容。
输入电容
The amplifier's input capacitance should be as low as possible.
放大器的输入电容应尽可能低。

capaci- 像 capacity(容量),电容就是“容纳电荷的容量”;想象一个容量瓶在存储电荷,拼写也就记住了。
语域:neutral 常见场景:物理教科书、电子技术手册、电路设计说明 该词是专业术语,多用于物理、电子工程等技术文档或教材,日常对话中较少出现。
没有常用词与 capacitance /kəˈpæsətəns/ 完全押韵。resistance /rɪˈzɪstəns/、assistance /əˈsɪstəns/、appearance /əˈpɪrəns/、acceptance /əkˈsɛptəns/、importance /ɪmˈpɔːrtəns/ 都是 -ance 拼写形似词,但重读元音和结尾读音不同。capacity /kəˈpæsəti/ 与 capacitance 共享开头的 /kəˈpæs-/ 和拼写 capac-,但结尾是 /-əti/。
