纳欧 (nΩ) 单位定义
The nanoohm is a multiple of the unit ohm (Ω) for electrical resistance. The International System of Units (SI) defines the prefix nano (n) as a factor of one billionth or 10-9 or 0.000000001. Per this definition, one nanoohm is 10-9 ohms. The nanoohm is represented by the symbol nΩ.

The siemens (S) is the SI derived unit of electric conductance and admittance, also known as the mho (ohm spelled backwards, symbol is ℧). It is the reciprocal of resistance in ohms (Ω).
功率作为电阻的函数
The power dissipated by a resistor may be calculated from its resistance, and the voltage or current involved. The formula is a combination of Ohm's law and Joule's law where: P = V ∙ I = V2⁄R = I2 ∙ R. Where:
P是幂
R是电阻
是电阻两端的电压
是通过电阻器的电流
A linear resistor has a constant resistance value over all applied voltages or currents. Many practical resistors are linear over a useful range of currents. Non-linear resistors have a value that may vary depending on the applied voltage (or current). Where alternating current is applied to the circuit (or where the resistance value is a function of time), the relation above is true at any instant but calculation of average power over an interval of time requires integration of instantaneous power over that interval.
由于欧姆属于相关的单位系统,当这些量中的每一个都有其对应的SI单位(P代表瓦特,R代表欧姆,V代表伏特,I代表安培时,这个公式在数值上仍然有效当这些单位被使用时(并被认为被取消或省略)。
