A diode is a two-terminal semiconductor device that works as a one-way switch mainly for current within a circuit. The diode allows the flow of current easily within a single direction and restricts the flow of current severely from supplying in the other direction. This can be called a uni-direction device and it can be used as a rectifier within the electronic circuit. Generally, the diode works in a forward-bias condition whereas in a reverse-bias condition, current does not supply throughout … [Read more...]
