Someone who’s not very bright is dim or a dimwit. When things are hopeless, they’re dim too. For example, if a football team is losing by fifty points, their chances of winning are dim.
What is a dimmer in lighting?
Dimmers control the brightness of the light bulbs in your home. They work with many common fixtures, and you can use them to quickly enhance the ambiance of a room. Dimmed bulbs also conserve energy. There are a few important things to consider before you install a dimmer switch.

What is the dimmer in a car?
The headlight dimmer switch is the electrical switch that is used to control the vehicle’s headlight functions. The dimmer switch is primarily used to switch between the high and low beam headlights, however in many vehicles it also controls the vehicle’s interior lights as well.
What does dimmer AC mean?
AC current has a varying voltage polarity on a sine wave. With a dimmer switch, this regular sine wave or curve is chopped up deliberately. When the current changes direction, the light bulb circuit is automatically shut off.
Why does the bulb get dimmer?
After some time, when heater coil becomes hot its resistance increases. As a result, current through the heater coil decreases and the current through the bulb filament increases and thus dimness of the bulb decreases.
How does a AC dimmer work?
With a dimmer switch, this regular sine wave or curve is chopped up deliberately. When the current changes direction, the light bulb circuit is automatically shut off. The change in direction takes place when there’s zero voltage which happens twice in every cycle (120 times per second).
Which is the best definition of a dimmer?
Freebase(0.00 / 0 votes)Rate this definition: Dimmer. Dimmers are devices used to vary the brightness of a light. By decreasing or increasing the RMS voltage and, hence, the mean power to the lamp, it is possible to vary the intensity of the light output.
What do you need to know about the D dimer test?

What does a dimmer switch on a headlamp mean?
A switch used to select between the low and high headlamp beam on a road vehicle. (usually as “dimmer switch”, primarily in North America; elsewhere “dipswitch” or “dipper switch”) Dimmers are devices used to vary the brightness of a light.
What is the function of dimmer?
Dimmers are devices connected to a light fixture and used to lower the brightness of light. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.
Does a dimmer save energy?
Yes, dimmers save energy. Modern dimmers save more energy than older (rheostat) dimmers, but both save energy. Modern dimmers use a ” triac “, which is an inexpensive way of reducing power by pulsing the current.
Does a dimmer reduce voltage?
Typical dimmers reduce the RMS voltage heading to a light to dim it; this can be done by simple resistors or by chopping the top part of the waveform. So a dimmable LED light fixtures must have the ability to}: • Deal with a wide range of source voltage including part-formed sine waves, which is not easy for the control logic.
