How much electricity does your tv use?

Answer 1

Television AmperageGet a clamp on meter and clamp it around the hot wire only. This will give you the amperage if you don't know how to do the calculation. But a tv doesn't pull enough amperage to worry about. Additional InputIf you do need this info for calculating loads, as for example on an extension cord, power strip, or a surge protector, there are two ways I can think of that will provide the Ampere draw of a TV.

First, check for a label, decal, sticker, or even embossed into the TV housing. Usually, the power requirements are on the device. Also, usually, the label will show either Amps used, OR Watts.

If the label only gives Watts, to calculate Amps, DIVIDE the indicated Watts on the label by the indicated VOLTAGE, which will results in Amps.

Answer 2

Electricity has several units of measure, depending upon what you are trying to quantify. In the US, the voltage of the TV would be around 120V. The amperage would likely be around 2A or a little more. The power would be equal to the voltage times the amperage.

The answer varies widely, depending on how old your TV is, what size it is, and the kind of TV it is.

First, bigger roughly equates to more power used if the TVs are the same type

Second, the types are:

CRT- the old heavy boxes that are almost gone. They use the most power

Plasma- Flat screens, but heavier and thicker for a given screen size. These still use more power than LCD

LCD- Thinner and lighter and the most efficient power users in mass production today.

OLED- Not in mass markets yet, but promise to be very energy efficient.

Bottom line: Look for LCD TVs for now, and look online for specs as to power consumption.

One last issue: The cable or Satellite box that many of us use today often uses more energy than the TV that they serve. Even when 'off' they are very much on. To get an idea, just use your hand to feel the heat on top of the box when it has been off for a while. DVRs are the worst, since they have to be available to record at a moments notice

Answer 3

Average plasma: 350 watts

Average rear-projection: 212 watts

Average LCD: 213 watts

Answer 4

Highly variable - from about 10 in old sets (with tubes)

to about 1 for compact, solid-state new ones.

Answer 5

They all vary, but my current one uses about 3 amps.

How many amperes does a tv use?

Answer 7

55 watt
