  An induct or is an electrical component that stores energy in the form of a magnetic field . It is made up of a coil of wire that creates a magnetic field when current passes through it . An induct or is commonly used in electronic circuits to regulate the flow of current , as it can act as both a resistor and a capacitor . The most common use of an induct or is to act as a filter or regulator . It can be used to reduce the amount of current that passes through a circuit by creating a magnetic field around the coil . This magnetic field acts to oppose the flow of current , thus reducing the amount of current that can pass through . Ind uct ors are also used to store energy . They can be used in conjunction with a capacitor to create a reson ant circuit . This is a type of AC circuit that is used to generate a signal at a speci...

  The history of the LED ( light - em itting di ode ) bulb dates back to the early 1950 s , when Nick Hol ony ak Jr ., an engineer and inventor , first developed the technology . Hol ony ak created the first visible - spect rum LED , a red di ode , while working at General Electric ( GE ). His breakthrough set the stage for the development of the LED bulb . In 1962 , Robert Bi ard and Gary Pitt man , two Texas Instruments ( TI ) engineers , developed the first infrared LED di ode . While Hol ony ak ’ s LED was visible to the human eye , Bi ard and Pitt man ’ s LED was invisible . This was a significant step forward in LED technology , as it enabled the creation of sophisticated electronic circuits . In the 1970 s , research into LED technology continued at a rapid pace . In 1972 , M . George Cra ford , a scientist at Monsanto and TI , invented the first ...
