Emitting Diode (LED’s)
The bridge rectifier is designed with four LED’s internally arranged in a 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.
