Does a dimmed light save electricity?

Question

Does dimming the light save power? Thanks!

Answer 1

If in dimming the light you reduce the current, then yes.
Usually, resistance is increased by a variable resistor, and this reduces the current (although the resistor does dissipate some energy as heat).

Answer 2

Absolutely!!
Since light bulbs are rated in watts (which is a unit of work/energy per unit of time), then when they are receiving full power, they are using the full rate of work/energy.
By dimming the light, you are cutting down on the amount of power that is supplied, thus they are not using as much energy.
That's how a dimmer switch works, it increases the resistance, which decreases the voltage/amperage.

Answer 3

Pay attention The lights are not dimmed by a variable resistor, but by means of a chopper such as a triac or more complex circuits for dimmable fluorescent lamps.

Answer 4

It relies upon upon no remember if the enjoyed ones dimmer makes use of rectifiers or potentiometers (variable resistors that eat potential and supply off warmth). The dimmed bulb consumes much less potential and produces much less warmth and lightweight.

Answer 5

No. Might have been true for the old-fashioned wire-wound rheostats, but I think modern dimmers work on a circuit which simply inverts part of the current flow, but the rate of use of the current remains the same.

Answer 6

Absolutely. The dimmer the light, the less power it draws.

Answer 7

What a DIM question

Answer 8

yeah it can even a light not on can also save electricity as well.

Answer 9

yes because less electricity is being given off

Answer 10

yes
