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

所以,电感器反对电流的变化, 无论是增加还是减少。

Crash Course Physics 速成课物理

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。

Crash Course Physics 速成课物理

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

所以取下电池后,电感会 产生自己的电流!

Crash Course Physics 速成课物理

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。

Crash Course Physics 速成课物理

So let's sum up: Current in inductors lags voltage.

电感器中的电流滞后于 电压。

Crash Course Physics 速成课物理

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理, 让我们首先考虑直流电路中的电感器。

Crash Course Physics 速成课物理

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。

Crash Course Physics 速成课物理

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。

Crash Course Physics 速成课物理

For example, how are alternating currents affected when you add resistors? Or capacitors? Or an inductor?

例如,当您添加电阻器时,交流电会受到怎样的影响 ? 还是电容器? 还是电感?

Crash Course Physics 速成课物理

Another thing that sets inductors and capacitors apart from resistors is that they don't release a lot of heat.

将电感器和电容器与电阻器区分开来的另一件事是它们不会释放大量热量。

Crash Course Physics 速成课物理

When you switch a device on or off, and you notice a delay, that's probably because an inductor is in the system.

当您打开或关闭设备时,您会注意到延迟,这可能是因为系统中有一个电感器。

Crash Course Physics 速成课物理

So in AC circuit inductors, we say that the current and voltage are out-of-phase, which means they don't peak at the same time.

所以在交流电路电感中,我们说电流和电压是异相的,这意味着它们不会同时达到峰值。

Crash Course Physics 速成课物理

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。

Crash Course Physics 速成课物理

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

因此,在处理电感器时,您必须考虑时间。

Crash Course Physics 速成课物理

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。

Crash Course Physics 速成课物理

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。

Crash Course Physics 速成课物理

As the alternating voltage is applied across the inductor, the opposing emf that's induced equals the amount of voltage that drops across the device.

当交流电压施加在电感器上时,感应的反向电动势等于器件两端的电压下降量。

Crash Course Physics 速成课物理

By flipping the switch, you've either started or ended a voltage supply, but an inductor in the system delays the current from starting or stopping immediately.

通过拨动开关,您可以启动或终止电压供应,但系统中的电感器会延迟电流立即启动或停止。

Crash Course Physics 速成课物理

The inductor has an insignificant amount of resistance, so when it's the only device in the circuit, all the voltage must be opposed by the opposing emf.

电感器的电阻很小,因此当它是电路中唯一的器件时,所有电压都必须与相反的电动势相反。
