jual smart board.In order to make it easier for everyone to understand the process, Xiaobian will simplify the process of capacitive coupling, but it will also explain what is capacitive coupling. The capacitor is connected to the AC circuit, and the voltage of the circuit connected to one foot gradually rises, gradually accumulating the charge on the electrode plate, waiting for the voltage of the circuit connected to the foot to drop, and then returning the charge accumulated at the high potential back to the circuit. The same is true at the other end. The capacitor is insulated, and the entire capacitor does not pass current, but it accumulates and discharges the charge as the potential rises and falls, and the constant charging and discharging, which is equivalent to the current flowing through the capacitor, forms a path. (Ps: Coupling is the close cooperation between input and output)
