Two Input Nor Gate

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

Objective : To study Efficiency and Ripple factor in case of Half wave, Full wave and Bridge rectifier on application of load and filters. Features : Instrument comprises of AC Power Supply, 3 meters to measure Output Voltage, Output Current and ripple factor on electronic AC Voltmeter, 4 PN Junction Diodes, Filter Circuit kit, load Resistances selectable using bandswitch and all important connections points at 4mm Sockets. Optional Acc : Digital AC millivoltmeter.

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.

Objective : To plot Frequency Vs. Current Characteristics of LCR circuit when connected in series or in parallel. Features : Instrument comprises of 3 Resistances, 3 Capacitors and 1 Inductance connected inside and connections brought out at Sockets. 2 AC moving coil meters to measure voltage and current. Optional Acc. : Audio Frequency Function Generator
