How do I connect two DC power supplies in series?
373串联两个直流电源需要将第一个电源的正极连接到第二个电源的负极， 形成“菊花链”连接，串联电压为两个电源的电压之和。 串联两个直流电源的步骤如下： 请注意，负载的电压应当等于或高于两个电源的电压之和，以防损坏负载或电源。 此外，负载的额定...

我们通常将时间作为参考框架， 关注何时会发生某些特定事件。 这其中包括电气事件。 示波器使您能够查看特定电气事件的瞬时值（或某些其他事件通过适当的传感器转换而来的电压值）随时间的变化。 换句话说，我们可以使用示波器在时域中查看信号的波形。 傅立叶理论告诉我们，任何时域的电现象都是由一个或多个具有适当频率、幅度和相位的正弦波组成。 这也就是说，我们可以将一个时域信号转换为频域的等效信号。 频谱分析仪和信号分析仪可以在频域中测量每个特定频率的能量。

What is alternating current (AC)?
277Alternating current (AC) is a type of electric current whose polarity reverses periodically and whose amplitude varies continuously over time. AC power is often used in businesses and homes because it is cheaper and more efficient to generate and transmit than direct current (DC) power. During transmission, a transformer can reduce power loss by increasing or decreasing the voltage of the AC line. Alternating current (AC) is a form of household electricity -...
