most modern televisions are drawing electricity all of the time, so that the device can sense when a remote is used to issue a command to turn on. Also, part of the circuitry is kept charged all the time, to reduce the 'warmup' time between turning the unit on and seeing a picture.

∙ 16y agoMost if not all electronics use less electricity when turned off. When TVs are turned off, they simply draw small amounts of power so the memory (clock, settings etc.) of the TV remains intact.

Capacitors have a residual voltage when power is removed, unless something (such as a resistor) is used to discharge that voltage. The TV CRT (Picture Tube) is a VERY LARGE capacitor, with a VERY LARGE voltage. (25kV typically for a 25 inch set). There is generally no discharge circuit, so you MUST discharge the CRT before working on it. Additionally, due to capacitive memory, the CRT can regain part of its charge even after being discharged, so it is prudent to always discharge immediately before working on it.

What item that continues to use electricity even though its switch may be in the off position?
If a device is switched off at the wall, then that is equivalent of being unplugged and it will not use electricity. However any device with a transformer in it that is switched off at the device (not the wall) will continue to use electricity. Televisions etc are like this, so are mobile phone chargers.
Why might turning off the television and the lights help slow climate change?
Television and lights use electricity that is mostly generated by burning fossil fuel (coal, oil and natural gas). If this is the case, then one person turning them off reduces the demand on electricity a tiny bit. Now if a million people did it!
Is electricity wasted by simply leaving small appliances and table lamps plugged in if they do not have a pilot light or standby mode?
In short yes but it depends, mostly it's those appliances that use electricity in standby mode. The easiest way to tell is if it produces heat even when off. Run your hand over the top and feel for heat. TV's, computers, VCR's, DVD's anything with a timer or a clock and chargers for cellphones etc. Other things like lamps dont use electricity when plugged in. They cant because they use a simple circuit, it is either on or off.
Does it cost more money to turn off a tv when left a room and then back turn it back on in a few minutes or does it cost less money to just leave it on when left a room for a bit?
There are two factors to consider:1. How much money will be saved by the savings in electricity when the TV is off?2. Is the life of the TV reduced by turning it on and off frequently, so you will have to pay to repair or replace the TV sooner?It will usually cost less to turn the TV off if you will be gone more than a short time.see "Is it better to leave an electronic device on or to turn it on and off?"
Does an electrical receptacle draw power?
No the receptacle itself does not consume any power it is just a source of power. No amperage is used until the load is plugged in and turned on. Appliances plugged in with the switch in the off position draw no current. Devices that do not have an off- on switch will start drawing power as soon as they are plugged in. Once an appliance is switched on you are billed for the use of the electricity.
Do Hi-Def TV's use more electricity?
Typically, yes, they do--and they draw more power when in stand-by mode or "off" than regular TVs.
Why is a television warm to the touch after you turn it off?
If you just turned it off, it is because the motors and other electrical circuits and boards were running and just stopped. If it is a while after you turn it off, then the electricity is still feeding into it somewhere.
When a television is put into stand by does this mean that it still consumes electricity or is there no electricity usage?
A television that has been set into stand by mode will still use some electricity. The electricity usage is much less than if the television was fully on but more than if it was off.
What are the function of electronic parts of the tv?
Screen-To give off light. Speakers-To give off sound Remote control-To give off messages Remote Sensor-To sense the remote controls messages Cable-To pass through electricity to the television Plug-To receive electricity.
Why do people use too much electricity?
If you leave lights on when you are not using them and leave the TV on when you are not watching it, you are using too much electricity. You can actually cut your electric use and bill by shutting off lights when you are not using them, turning off appliances, including computers.
What are the functions of each electronic part of a TV?
Screen-To give off light. Speakers-To give off sound Remote control-To give off messages Remote Sensor-To sense the remote controls messages Cable-To pass through electricity to the television Plug-To receive electricity.
Do baseboard heaters continue to draw electricity when off?
Answer No, if the current to the baseboard heaters is off they can't run or heat.
Where can you find examples of radiation?
Televisions give off radiation Radios High Voltage Electricity PC's

Can you record a TV program while the TV is turned off?
NO, when you turn off the TV, the output of the TV will also go off.
What are the examples of conserving the electricity?
Turn the light off when you leave a room, turn things like TVs and computers completely off instead of leaving them in stand-by.
What happens if you unplug an HD tv while its on?
It turns off
