You can calculate the voltage drop across each resistor by using Ohm's Law, V equals I times R.

Now, in ohmic materials, we can use our new expression of Ohm's Law to predict and calculate the behavior of a circuit.

And then you just substitute Ohm's law in for every resistor's voltage, to get terms of current and resistance.

0。然后您只需将欧姆定律代入每个电阻器的电压，即可得到电流和电阻。

But since we don’t know the voltage drop across the internal resistance, you can use Ohm’s law, and substitute “current times resistance” for the voltage.

但由于我们不知道内阻两端的电压降， 您可以使用欧姆定律， 用“电流乘以电阻” 代替电压。

But since we don't know the voltage drop across the internal resistance, you can use Ohm's law, and substitute " current times resistance" for the voltage.

但是由于我们不知道内部电阻上的电压降，您可以使用欧姆定律并将电压替换为“电流乘以电阻”。

All you have to do is implement Ohm's law yet again, multiplying current and resistance in order to find the voltage drop.

您所要做的就是再次执行欧姆定律，将电流和电阻相乘以找到电压降。

Since you know the resistance of, and voltage across, each resistor, you just use Ohm's Law again to calculate the current through each wire.

因为您知道每个电阻器的电阻和电压，所以您再次使用欧姆定律来计算通过每条导线的电流。

In the mid 19th century, a German physicist named Gustav Kirchhoff expanded on the principles of Ohm’s law to improve our ability to calculate current and voltage in complex electrical circuits.

19 世纪中叶， 一位名叫古斯塔夫·基尔霍夫 (Gustav Kirchhoff) 的德国物理学家扩展了欧姆定律的原理， 以提高我们计算复杂电路中电流和电压的能力。

Here, the current through them – 0.41 Amperes – stays the same, while the voltage drop across each one can be found using Ohm's Law.

在这里，通过它们的电流 - 0。41 安培 - 保持不变，而每个电流的电压降可以使用欧姆定律找到。

If the voltage supplied by a battery is the equal to the sum of all voltage drops across, say, three resistors in a series, you can substitute Ohm’s law for each resistor.

如果电池提供的电压等于所有电压降的总和， 例如串联的三个电阻器， 您可以用欧姆定律代替每个电阻器。
