conductor length的用法和樣例：
例句
- We increase the length of the wire, thus increasing its resistance.
我們增加導線(xiàn)的長(cháng)度，從而增加了導線(xiàn)的電阻。 - The resistance of any length of a conducting wire is easily measured by finding the potential difference in volts between its ends when a known current is flowing.
已知導線(xiàn)中的電流，只要求出導線(xiàn)兩端電位差的伏特數，就不難測出何任長(cháng)度的導線(xiàn)的電阻。
