交流电适用于通过电网系统远距离输电和配电。

直流电是一种单向电荷流，比交流电更可靠，但不适合远距离输电。大多数电子器件都使用直流电，因为它们的电压是恒定不变的，例如使用电池供电的器件。有些器件也会使用整流器将交流电转换为直流电。电源通常具有内置整流器和变压器，可以将电压提高或降低到合适的水平。

If you want to measure current, voltage, etc., you need specialized measuring equipment. Analog and digital multimeters are usually used to measure current, but the circuit must be cut off and the multimeter and the circuit connected in series in order to make the measurement. However, it is not uncommon that it is not possible to disconnect the circuit in some cases. In addition, there is a danger of electric shock when the circuit is disconnected. In this case the clamp meter...

How to measure frequency? Measurable Devices, Measurement Methods, and Precautions In everyday life, many people say they don't know much about the frequencies of electrical appliances. However, some electrical appliances have specific compatible frequencies, and using electricity at a frequency that is not compatible with the product may lead to malfunctions, fires, and other risks. In addition, in industrial equipment, there are electrical designed to operate at fixed or variable frequencies...
