wisi electrical components are electronic devices made from semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes: the positive electrode, also called the anode; and the negative electrode, also called the cathode. When a forward voltage is applied across the two terminals of the diode, the diode conducts; when a reverse voltage is applied, the diode cuts off. The conduction and cutoff of the diode are equivalent to the closing and opening of a switch. The diode has unidirectional conductivity; when conducting, the current flows from the anode through the tube to the cathode. The diode is one of the earliest semiconductor devices, and its applications are very extensive. Especially in various
