Germanium Diode Unit

Bridge Rectifier is made of four diodes connected in a bridge circuit. It is housed in a plastic moulded box. This bridge rectifier converts alternating current (AC) into direct current (DC). It provides the same output polarity for either input polarity. All the electronic devices require direct current, so bridge rectifiers are used inside the power supplies of almost all electronic equipment. For the easy understanding of the internal circuitry, the circuit diagram is printed on the box.

Mounted on base, with 4 mm colour coded sockets, with circuit diagram printed for demonstration. Shows that resistance is inversely proportional to light density.

To study the EX-OR digital logic gate and verification of the truth table.
