2. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   When the dimmer is at 50% power, the switches are switching their highest voltage (>325 V in Europe) and the sudden surge of power causes the coils on the inductor to move, creating a buzzing sound associated with some types of dimmer; this same effect can be heard in the filaments of the incandescent lamps as "singing". The suppression ...

3. Joel Spira (businessman) - Wikipedia

   en.wikipedia.org/wiki/Joel_Spira_(businessman)

   Dimming lights with a solid state dimmer also reduces total power draw, unlike rheostat dimmers. Spira's design (and most modern dimmers) rely on the use of AC power, and on the characteristics of incandescent lights. Most importantly, incandescent lights take time to cool down when switched off, and so are much less prone to flickering than ...

4. Light switch - Wikipedia

   en.wikipedia.org/wiki/Light_switch

   Two light switches in one box. The switch on the right is a dimmer switch. The switch box is covered by a decorative plate. The first light switch employing "quick-break technology" was invented by John Henry Holmes in 1884 in the Shieldfield district of Newcastle upon Tyne. [1]

5. Electrical ballast - Wikipedia

   en.wikipedia.org/wiki/Electrical_ballast

   A dimmable ballast is very similar to a rapid start ballast, except that the autotransformer is connected to a dimmer. A quadrac type light dimmer can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled. A resistor of about 10 kΩ is required to be connected in parallel with the ...
