👉 In electronics, a diode is a type of electronic component that allows current to flow only in one direction. It is characterized by its high resistance and low breakdown voltage. The term "duodiode" refers to a diode with an open circuit potential difference between the two electrodes, which is typically equal to 0 volts. This makes it essentially an open circuit, allowing electrons to pass through without being blocked or stopped. A diode can be used as a switch or a voltage regulator in
