• When a load is connected to the source terminals (the circuit is then said to be loaded) and the circuit is closed, a current begins to flow round it. Now the voltage between source terminals 1 and 2 (called the terminal voltage) is not equal to its e.m.f. because of the voltage drop VS inside the source, that is, across the source resistance RS VS=RSI

接得到的电阻是1/(1/10+1/22+1/47)=5.997欧姆。

2.电阻和功率 下面讨论电阻器的功率性能。在电炉灶面、烤箱、电暖炉、 电水壶和烘箱上设置电阻器,其目的是利用它处理和消耗很大的 功率。这些电器都是根据某些物质的这一功率性能而制成。 从欧姆定理(dìnglǐ)我们知道:P=I*I*R,即功率等于电流的平 方乘以电阻。上面例子中,三个电阻器串联得到79欧姆电阻器, 如果在它们上面加上24伏特电压,从欧姆定理就可知流过的总电 流:I=V/R=24/79=0.304安培。 用任何功率公式我们都可以确定0.304安培的电流流过79欧 姆的电阻总共要消耗7.3瓦特的能量!而且,当电阻器上的电阻大 小不等时,电阻越大,消耗的能量也就越多。

Notes
[2] Resistors which are deliberately designed to handle and radiate large amounts of power are electric cooktops, ovens, radiators, electric jugs and toasters. 本句的主语是Resistors,定语从句“which are deliberately designed to handle and radiate large amounts of power”修饰Resistors。在该定语从句中,to
handle and radiate large amounts of power是一个动词不定式短语,做目的 (mùdì)状语,修饰谓语are designed。
