Q2
强电一般是电力系统中的电,比如说220v的照明电,以及1000多v的工业用电等,强电的特点是电压高,频率低,电流大,强电是用来驱动大功率的电力设备的。比如说电动机,电灯等用电设备。(Strong power is generally the electric power system, such as 220v electrical lighting, and more than 1,000 v industrial electricity, etc., characterized by strong electric high voltage, low frequency, current, strong electric power is used to drive the electrical equipment. For example, motors, lights and other electrical equipment.)
