交流（AC）是一种极性周期性地反转并且幅度随时间不断变化的电流。 与直流（DC）电相比，交流电的发电和输电成本更低，效率更高，因此企业和住宅通常使用交流电。 在传输过程中，变压器可以通过提高或降低交流线路的电压，降低功率损耗。
交流电是一种家用电能——当消费者将电视等家用电器和其他器件的电源插头插入墙壁上的插座时，便能使用交流电。交流电可以转换为直流电，供几乎所有电子器件使用。
This article will detail the basics of a clamp meter and the principles of measurement. When it comes to instruments that measure current, many people may think of analog or digital multimeters. However, if you want to make measurements without breaking the circuit, a clamp meter is recommended. Direct wiring method ...

View Full VersionIts advantages include: Ultra-low jitterTrueform function/arbitrary waveform generators have jitter as low as 1 ps and excellent edge stability. You can even use them as system clocks for timing and triggering other instruments. Thanks to better jitter performance, you can locate edges more accurately, which helps reduce timing errors in circuit design. Ultra-low...
View Full VersionWhat is resistance in electricity? This article will cover the basics of resistance, how to calculate resistance, and resistors. Many people have heard the word "resistance" when they were students, but may still not understand it. However, because they don't understand it, they are hesitant to ask people about it now. Simply put, resistance is a force that flows in the opposite direction of the current. Resistance...
