抵抗器
解説 Definition
resistors は resistor（抵抗器）の複数形です。電気回路で電流の流れを制限したり調整したりする部品を指します。電子工作や回路設計の説明でよく使われます。
Resistors is the plural form of resistor. It refers to electrical components designed to provide resistance in a circuit, thereby limiting current, dividing voltage, setting operating conditions, or otherwise controlling electrical behavior.
覚え方のコツ Memory Tip
resistors は単数形 resistor に規則的な複数語尾 -s を付けた形で、語尾は /z/ と発音します。resist「抵抗する」＋-or「働きをする物」から、電流の前に立ちはだかって流量を制限する部品と覚えます。two resistors、current-limiting resistors、place resistors on the board のように、回路図や基板の場面と結び付けましょう。
Start with resist, “oppose,” and the device-forming ending -or: a resistor is something that resists the flow of electric current. Add the regular plural -s, pronounced /z/, to get resistors. Visualize several small components placed on a circuit board, each standing in the current’s path and controlling how much can flow. Useful combinations include two resistors, current-limiting resistors, and resistors connected in series. Do not confuse electrical resistance with physically blocking all current: a resistor normally limits or regulates current rather than stopping it completely.
例文
The circuit uses two resistors and one LED.
その回路は抵抗器を2つとLEDを1つ使っています。
Please place the resistors in the correct positions on the board.
基板上の正しい位置に抵抗器を配置してください。
Different resistors can change how much current flows through the circuit.
異なる抵抗器を使うと、回路を流れる電流の量を変えることができます。

resistors の語源・成り立ち Etymology
resistors は resistor「抵抗器」の複数形で、resist「抵抗する」+ -or「するもの」+ -s から成ります。resist はラテン語 resistere に由来し、re-「逆らって」+ sistere「立つ」で、「立ちはだかるもの」だから電流への抵抗器です。関連語は resist、resistance。
Resistors is the regular plural of resistor, a formation from resist plus the agent or instrument suffix -or. Resist comes from Latin resistere, “to stand back, withstand, or oppose,” combining re- with sistere, “to cause to stand” or “take a stand.” In electrical terminology, resistor names a component that provides resistance to current. The plural ending -s indicates more than one such component and is pronounced /z/ in this word.
