(" I just felt that it was taking place at times, very definitely." )

我就是觉得有有电感应，非常肯定。)。

Inductance, by the way, is expressed in units called Henrys.

顺便说一，电感 称为亨利的单位表示。

So to get a handle on how inductors work, let's first consider one in a DC circuit.

因此，要了解电感器的工作原， 让我们首先考虑直流电路中的电感器。

So you have to consider time when you're dealing with inductors.

因此，在处电感器，您必须考虑间。

That's because the inductor opposes the sudden change in current that was caused by the sudden voltage change.

这是因为电感器对抗由电压突变引起的电流突变。

And because we have an inductance L and a resistance R, we call this configuration an LR circuit.

因为我们有一个电感 L 和一个电阻 R，所我们称这种配置为 LR 电路。

Let's say this circuit has an inductor connected in series with a battery that has a constant voltage, V naught.

假设这个电路有一个电感器与一个具有恒定电压 V naught 的电池串联。

Capacitors usually have a tolerance of around plus or minus 10%, and for inductors, it's often within plus or minus 15%.

电容器的容差通常在正负 10% 左右，而电感器的容差通常在正负 15% 内。

There's no longer a changing current, so the inductor acts just like a piece of wire.

不再有变化的电流， 因此电感器就像一根电线。

So after the battery is removed, the inductor generates its own current!

所电池后，电感会 产生自己的电流！

Because, remember, the inductor opposes the change in current with its own changing magnetic flux.

因为，请记住，电感器通过其自身变化的磁通量来对抗电流的变化。

Since most inductors have a natural resistance, we'll say that there's also a small resistor in series with the inductor and battery.

由于大多数电感器都有一个自然电阻，我们会说还有一个小电阻器与电感器和电池串联。

So, inductors oppose a change in current, whether it's an increase or a decrease.

所，电感器反对电流的变化， 无论是增加还是减少。

L is a constant, known as the inductance, signifying how well that specific coil induces an opposing current, depending on its shape and size.

L。L 是一个常数，称为电感，表示特定线圈感应反向电流的程度，具体决于其形状和大小 。

For inductors and capacitors, however, the story's a little different.

然而，对于电感器和电容器，情况 有所不同。

I have solar on the roofs, batteries in the garage, electric heat pumps for air and water heating and air conditioning, electric induction, cooktop stoves.

我在屋顶上有太阳能， 在车库里有电池，用于空气和水加热和空调的电热泵，电感应， 炉灶。

Engineers have been continuously innovating; making microchips, resistors, capacitors, inductors, and connectors as small as possible- some of these components are smaller than a flea.

工程师们一直在不断创新；制造尽可能小的微芯片、电阻器、电容器、电感器和连接器——其中一些元件比跳蚤还小。

The second invention is worn like a piece of jewelry-a flexible ring embedded with a wireless electrocardiogram sensor that can also diagnose heart irregularities, as well as other conditions.

第二项发明是能够戴在手上非常柔软的一种戒指，它的内部具有能够诊断脏异常等症状的无线电感应器。

Now let's go back to AC circuits, and combine an inductor, a resistor, and a capacitor all in one circuit.

现在让我们回到交流电路，将电感器、电阻器和电容器组合在一个电路中。

So I read where I can, but I have a favorite place and probably you do, too—a place where the light is good and the vibe is usually strong.

所，只要能读书的地方我都读，但我有个最喜欢的阅读地点，很可能你也有这么个去处——那里灯光明亮，电感应的讯号特别强。
