How much power does a small transformer consume if it is plugged in but not doing anything?

Hi all,

I hope everyone would be aware of the term TRANSFORMER... anyways, will give you a brief idea about the term...

I could tell you the plenty of operations which the transformer does, among them its mainly used to convert a AC Current to minimal DC voltage. Most transformer cubes that you find around the house produce a low-voltage DC current (3 to 12 volts, and less than an amp of current). DC current is necessary because rechargeable batteries store DC current, because most electronics require low-voltage DC current and because small DC motors run directly from batteries and are the least expensive motors available.

Hope this information is enough!! We shall discuss our topic in detail now,

As said, transformers have been used by various devices,lets say for ex: printer, scanners,speakers, answering machine, cordless phone, electric screwdriver, electric drill uses Transformer as a source for them...

Do you know, by just connecting a transformer to the AC switch would consume power...
It would consume more power if its connected to other devices during charging of materials. If you have ever felt one and it was warm, that is wasted energy turned to heat. The power consumption is not large -- on the order of 1 to 5 watts per transformer. But it does add up. Let's say that you have 10 of them, and they consume 5 watts each. That means that 50 watts are being wasted constantly. If a kilowatt-hour costs a dime in your area, that means you are spending a dime every 20 hours.

Hope you have STABILIZERS connected either with TV or Fridge, isnt it?

Wait... You may think why do i ask the above stupid question, isnt it ? :)

Hmmm! my question would make sense... read below,

Nowdays, people have forgotten the habit of Switching OFF the TV properly from the MAIN SWITCH. Have you seen these cases? The TV LED will be in RED eventhough the screen is blank, in this case, the TRANSFORMER utilizes the power for charging the circuits, since its connected with AC power directly... the end result, your METER BOX will be running like a black HORSE! :)

I would suggest you, do SWITCH off the appliances which you use TRANSFORMERS as a source,Stabilizer is a real time example for it... so... lets not forget the STABILIZER case... ;)

If you dont agree with my points, pl tell this buzzword along with me,

" I am ready to give my half of the salary to the ELECTIRICITY dept" ... :) ha ha!


Hope you are clear with the confusion we had been from a long time...

Will meet you with another nice topic!
