Two Input or Gate

Bridge rectifier is designed with four LED’s internally arranged in bridge pattern fitted inside a plastic moulded case. Two LED’s are red and two LED’s are green. This device is used to demonstrate the functioning of a bridge rectifier, i.e., to convert alternating current (AC) into direct current (DC). Two yellow sockets are used for AC input. Two sockets, one red and one black, are used for DC output. For the easy understanding of the internal circuitry, the circuit diagram is printed on the box.

Mounted on transparent covered base for easy demonstration. Diagram and two sockets are provided for use with some circuit. Thermistor is mounted above the base to avoid the damage from heat.

Mounted on transparent covered box. Diagram provide with three different color four mm sockets for easy identification of terminals.

To study the AND digital logic gate and verification of the truth table.
