向您学习,及时提醒我应该注意的交流方式。
Power comes in through the socket and enters the transformer, which is typically an iron core with coils of copper wire wound tightly around it. One rather odd thing about a transformer is that, to look at how it's made, one would think that the power couldn't get out of the wall and into the circuits, because the wire that runs the power from the wall into the transformer simply makes a series of turns around the transformer core and then leaves for the wall, with no interconnection to the other wires on the transformer core. Thanks to the property of inductance, however, what is actually happening is that energy running through this winding of the transformer induces a field around the other windings, and causes current to flow in them. The result is that the AC from the wall is turned into AC of whatever voltage or voltages are required.
全文是这段。

意义是这段。

电无法从墙壁出来进入电路?
我理解,电是指所有电特性,即我们现在交流电网中的实际电能,这存在千差万别的特性。
The result is that the AC from the wall is turned into AC of whatever voltage or voltages are required.
其结果是从墙壁而来的,交流电也有可能是不理想的的交流电最终转变为电压。(我理解)
也就是说,电源线带有的特性阻抗,以及电源电路的工作特性,最终都将影响电路性能? |
