Designers of early indoor LED light bulbs faced numerous technical hurdles, including AC-to-DC conversion, thermal heat-sinking, constraints imposed by current bulb sizes, electrical transients, and ...

This electronic lighting dimmer circuit is used to control the lamp for arbitrary brightness. This electronic lamp dimmer circuit work for incandescent lamp, not a fluorescent one. The dimmer circuit ...

Way back when [Ms Ellsworth] was a kid, she kept seeing the same circuit over and over again in her various op-amp books. It was a Wien bridge oscillator, a small circuit that outputs a sine wave with ...

A recent discussion with Scott Brown of iWatt revealed some interesting facts about the design of IC drivers for consumer LED lighting. Although LED lifetime can reach about 20 years and the power ...

You're probably familiar with the old-fashioned strings of holiday lights that go out completely if one bulb burns out. Although these lights cause hours of frustration during the holidays, they also ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.
