欧姆电阻单位,一段导体两端的电位差为伏特时产生一安培电流,那么这段导体的电阻就等于欧姆 A unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals.
欧姆,格奥尔格·西蒙1789-1854德国物理学家,因其对于数学、声学和电阻测量做出的贡献而著名 German physicist noted for his contributions to mathematics, acoustics, and the measurement of electrical resistance.
每一盏灯泡有120欧姆的电阻。 Each of the bulbs has a resistance of120 ohms.
