Diodes are used in all electronic devices but now mostly these are replaced by LEDs. Why is it going so? How are these better than ordinary diodes? A diode allows electricity to flow in one direction only and blocks the flow in the opposite direction. They may be regarded as one-way valves and they are used in various […]
