Individual cells can be connected in series or parallel to build up either voltage or current.

单个电池可以通过串或方式形成电压或电流。

It has two batteries and four resistors, with a combination of series and parallel connections.

它有两个电池和四个电阻，采用 串和组合。

But! What happens when you create circuits that are combinations of series and parallel connections?

但！当你创建电路时会发生什么 是串和组合吗？

And in the case of parallel connection, you want to pay close attention to the principle known as the conservation of charge.

在情况，您要意称为电荷守恒原理。

Well, if you have several capacitors connected in parallel, the overall capacitance of the circuit increases.

好吧，如果你有几个电容器，电路总电容会增加。

You’ve learned how to simplify circuits with resistors connected in series and parallel with a single battery source, which is great!

您已经学习了如何使用串和连接电阻器与单个电池电源来简化电路， 这太棒了！

Note that this is the not the same as the parallel equation for resistors!

请意，这与 电阻方程不同！

You've learned how to simplify circuits with resistors connected in series and parallel with a single battery source, which is great!

您已经学会了如何使用与单个电池电源串和电阻器来简化电路，这太棒了！

The other branch has a 6 Ohm resistor, and then another parallel formation of resistors, 3 and 5 Ohms each.

另一个分支有一个 6 欧姆电阻器，然后是另一个电阻器，每个 3 和 5 欧姆。

In terms of electricity, this means that for every branch in a parallel connection, the voltage is the same, no matter what the resistance is.

就电力而言，这意味着对于连接任何分支，无论电阻如何，电压都是相同。

This shows you that the equivalent resistance for a parallel setup of resistors will actually be smaller than any one of the resistors in the circuit.

这表明电阻等效电阻实际上小于电路中电阻等效电阻。

And you do it that way, because you know that any components connected in parallel will have the same voltage.

你这样做是因为你知道所有组件都将具有相同电压。

Using our equation for resistors in parallel, you find that they simplify to a single resistor of about 1.88 Ohms.

如果您使用我们电阻方程，您会意到它们简化为约 1。88 欧姆单个电阻。

Think about the outlets in your house – they’re all connected in parallel, so no matter how many items are plugged in, they all receive the same voltage.

想一想你家里插座——它们都是， 所以无论插入多少东西， 它们都会接收到相同电压。

Our 1.88 Ohm resistor is a combination of a 3 Ohm and 5 Ohm pair of resistors in parallel.

我们 1。88 欧姆电阻器是 一对3欧和5欧电阻。

Think about the outlets in your house – they're all connected in parallel, so no matter how many items are plugged in, they all receive the same voltage.

想想你家电源插座——它们都是，所以无论插入多少东西，它们都接收到相同电压。

And since every point of a conductor has the same potential, and all the conductors are connected, all devices connected in parallel will have the same voltage.

而且由于导体每个点都具有相同电位，且所有导体都连接在一起，因此所有连接设备将具有相同电压。

Now, let's combine the 17 Ohm and 7.88 Ohm resistors, which are in parallel, into one resistor and its resistance turns out to be 5.38 Ohms.

现在让我们将 17 欧姆和 7。88 欧姆电阻组合成一个电阻，其阻值为 5。38 欧姆。

We also discussed how capacitors function in a typical DC circuit and the ways they behave when combined in series and parallel connections.

我们还讨论了电容器在典型直流电路中作用以及它们在串和连接时行为方式。

And since the voltage for each resistor is the same in parallel, you can cancel the voltage term out of the entire equation and we’re left with the equation for parallel equivalent resistance.

由于时每个电阻电压相同， 您可以从整个等式中取消电压项， 剩等效电阻等式。
