Guru Prakash Pretzel was  meditating, and all he said was " Ohm… ohm… " " Ohm? " wondered Mr. Buckmeister.

古鲁普拉卡什·普雷结 (Prakash Pretzel) 正在冥想，他说的只是“欧… … 欧… … ” “欧？ ” 巴克迈斯特先生想知道。

67 volts divided by 3 Ohms gives you a current of 0.56 Amperes through the 3 Ohm resistor.

1。67 伏除以 3 欧给一个电流 0。56 安培通过 3 欧电阻器。

In this case, you add the 15 and 2 Ohm resistors into a single, 17 Ohm equivalent resistor.

在这种情况下， 15 和 2 欧的电阻器 成一个 17 欧的等效电阻。

And 0.41 Amperes times 2 Ohms equals the remaining 0.82 Volts across the 2 Ohm resistor.

0。41 安培乘以 2 欧等于剩下的 2 Ohm 电阻上的电压为 0。82 伏。

So let's start by turning the parallel connection of the 3 Ohm and 5 Ohm resistors into one equivalent resistor.

让我们首先将 3 Ohm 和 5 Ohm 电阻并联成一个等效电阻。

In order to complete the rest of the circuit, let's expand the 5.38 Ohm resistor back out again, to those two resistors in parallel.

为了完成电路的其余部分，让我们将 5。38 欧电阻器扩展回这两个并联电阻器。

Now, you know that any two resistors in parallel have the same voltage drop, so both the 17 Ohm resistor and the 7.88 Ohm resistor have a voltage drop of 7 Volts, just when they were collapsed into one.

现在知道两个并联运行的电阻器具有相同的压降，因此 17 欧电阻器和 7。88 欧电阻器在折叠成一个时都有 7 伏的压降。
