先理解核心含义,再看它在真实句子里的用法。
电容器
an electrical device that stores an electric charge
You need to charge the capacitor before testing the circuit.
测试电路前,你需要给电容器充电。
An electronic component capable of storing electrical energy in an electric field; especially one consisting of two conductors separated by a dielectric.
一种电器设备,以其储存电荷的能力为特征
an electrical device characterized by its capacity to store an electric charge
The technician replaced the faulty capacitor in the power supply.
技术员更换了电源中损坏的电容器。
You should discharge a capacitor before touching its terminals.
在触碰电容器端子之前,应该先给它放电。
This small capacitor stores enough energy to keep the clock running.
这个小电容器储存的能量足以让时钟继续运行。
charge 在这里作动词,表示“给……充电”,后接电容器等储能器件。
You need to charge the capacitor before testing the circuit.
测试电路前,你需要给电容器充电。
discharge 意为“放电”,是处理电容器时确保安全的重要操作。
Always discharge the capacitor before removing it from the board.
从电路板上取下电容器之前,务必先将其放电。
数值单位(如 µF 微法)直接放在 capacitor 前作定语。
Use a 10 µF capacitor for this part of the circuit.
在电路的这个部分使用一只10微法的电容器。
Not this
The charge in the capacitor is 5 coulombs.
Use this
The charge on the capacitor is 5 coulombs.
电容器的电荷位于极板表面,因此用介词 on 表示“在……上”;in 指内部空间,不符合物理意义,所以应把 in 改为 on。
Not this
The function of a capacitor is store electrical energy.
Use this
The function of a capacitor is to store electrical energy.
“The function of A is to do…”结构中,作表语的不定式必须带 to,不能省略,因此 store 应改为 to store。
Not this
This circuit needs a 10-microfarad capacity.
Use this
This circuit needs a 10-microfarad capacitor.
capacity 指“容量/电容值”,表示电子元件本身时应使用 capacitor;说“一个 10 微法的电容器”要用 a 10-microfarad capacitor。
Focus on the distinctions below. Other candidates are kept compact until a reliable usage note is available.
给电容器充电
The circuit charges the capacitor to five volts.
该电路将电容器充电至5伏。
使电容器放电
Always discharge the capacitor before repairing the device.
修理设备前务必给电容器放电。
电容器组

电源使用电解电容器来减小电压纹波。
陶瓷电容器
Ceramic capacitors are often used in high-frequency circuits.
陶瓷电容器常用于高频电路中。
通量电容器就是能实现时间旅行的装置。
Doc Brown says this while showing the DeLorean's time circuit in the 1985 film Back to the Future. This fictional capacitor is the central gadget of the movie's time travel.
这是1985年电影《回到未来》中布朗博士在展示德罗宁汽车的时光回路时说的话。这个虚构的电容器是影片中时间旅行的核心装置。
Use capacitors naturally, then get feedback on meaning, tone, grammar, and phrasing.

记忆联想:capacitor 与 capacity(容量)同以 capac- 开头,电容器就是一个能储存电荷的‘容量器件’。
语域:neutral 常见场景:electronics、electrical engineering、physics education、product manuals 电容器是电子学和电气工程中的标准技术名词,多用于专业教材、电路图、产品说明书等场合,也可在日常生活讨论电器时使用。该词正式程度适中,没有明显口语或俚语色彩。
这些词都含有相同的拼写片段 -itor,但没有任何一个与 capacitor /kəˈpæsətɝ/ 押韵:它们的重读元音都不相同(如 monitor /ˈmɑːnɪtər/、editor /ˈedɪtər/)。capacitor 的重读元音是 /æ/,结尾为 /sətɝ/。
