The circuit of the neck of the card, the roundabout power supply line was ubiquitous. This terminal voltage is generally low at the peak, easily lead to refrigerators, air conditioners, washing machines and other household appliances due to excessive current burned, TV and other audio-visual equipment, often due to ...
