How many amps does a TV use?

When it comes to power use, televisions are rather energy efficient. Many people are interested in the energy requirements of their television sets, not only in off-grid situations. Most of them also want to discover How many amps does a TV use in order to more precisely estimate their monthly energy expenses.

A television’s watt may be calculated in a variety of methods. Furthermore, some TVs are connected to external sound systems, which often use more power than the televisions themselves. Although it is important to understand how much electricity your television uses in order to properly manage your energy consumption,

In this article, we’ll go through how to calculate how much energy your TV use.

What Exactly Are Amps?

Electrical current is measured in amperes (abbreviated as amp), which are units of measurement. The most straightforward approach to comprehend what this really implies is to use the analogy of water, since electricity, after all, is a flow in some sense.

The number of amps in an electric line is equivalent to the number of liters of water that pass through it every second. Water can flow at various rates within a certain radius until reaching its maximum capacity before bursting open. Like that, electric wires can tolerate currents up to a specific level that is determined by the diameter, or gauge, of the wires being used in the circuit.

If the current flowing through a wire exceeds the capacity of that wire, it will literally explode into flames. There are many uses for determining how much power a television set consumes in amps. The house environment dictates the thickness and thinness of the wires that can be used for electrical installation.

The time it takes to run a TV off-grid and with a battery can be decided by the TV’s battery life. The capacity of a battery is typically stated in milliamp-hours or amp-hours, depending on the manufacturer. As a result, dividing this figure by the maximum amperage of a television set will tell you the least number of hours the TV set can operate on that battery.

How many amps does a television consume?

A typical flat-screen television needs just one ampere to run, which is why an RV van can contain a working medium-sized television. However, it is important to find out how much power your television consumes so that you can better control your energy usage.

The number of watts that a television consumes is dependent on a number of variables. The screen of the television is the most important element to consider. Because it is the biggest component and does the most of the work, the television screen uses the most energy. Other variables that affect the number of Amps that a television consumes are as follows:

  • Screen technology
  • Volume
  • Backlight
  • Display size
  • Brightness
  • Contrast
  • Integration features
  • Smart TV capability

The most important factors to consider are the display size and screen technology.

The size of the display

The typical American television is 50 inches in size and consumes 0.95 amps while operating at 120 volts. This equates to an average TV power usage of 113 watts on a typical day. In a given year, the typical television will use 142 kWh and cost little more than 17 dollars (assuming 5 hours of use per day).

Amazingly, the average television screen size in the United States has more than doubled between 1998 and now, increasing from 23 to 50 inches.

When attempting to estimate how many amps a TV consumes, it is critical to know the typical TV size. Smaller televisions will use much less electricity, whereas bigger televisions will consume significantly more. Due to the fact that bigger televisions have greater power consumption needs, this is the case. For example, a standard 85”-inch television consumes more than 400 watts, while a 43″ television consumes as little as 100 watts.

Technology based on screens

The component that consumes the most power in a television is the screen technology. This is due not only to the fact that it is the largest component, but also to the fact that it does the bulk of the labor. As a result, it has the greatest impact on power use.

Plasma televisions use the greatest consistent amount of power per square inch, while micro displays use the fewest consistent powers per square inch.

A 46-inch plasma panel has a viewing area of about 906 square inches and uses around.30 to.39 watts per square inch of viewing space. Amps are equal to watts divided by volts, thus 0.35(906)/120=2.6425 amps is the watts divided by volts equivalent. 2.6425 amps are used by a plasma television.

A microdisplay rear projector television uses the least amount of energy when measured in watts per square inch, translating to 0.13(906)/120=0.9815 amps for a 46-inch microdisplay, or less than half the amps needed to run a plasma television. Other sources claim that LEDs are even more energy efficient, using just one-fourth the power of a plasma television.

LCD TVs use a wide range of power, ranging from 0.16 to 0.41 watts per square inch. As a consequence, depending on the type, a 46-inch LCD panel may use as little as 1.208 amps or as much as 3.1 amps. Traditional cathode-ray tube TVs use 0.25 to 0.40 watts per square inch, resulting in a current rate of 1.8875 to 3.02 amps for a 46-inch screen. It may actually make them more energy efficient.

The microdisplay television is the most energy-efficient television on the market, drawing the least amount of power. Plasmas and liquid crystal displays (LCDs) use two to three times the amount of energy and current as traditional displays. LG and Samsung use different LEDs for their television backlights, and although they both produce LED TVs, their audiences are very different.

LCD, LED, OLED, QLED, and other display technologies are the most widely used nowadays, with plasma displays and, in particular, CRT (Cathode Ray Tube) screens being phased out of the market.

Checking the power requirements of any television unit is the best way to discover their EXACT power requirements. To do so, look at the label on the back of the television and/or the paperwork that came with the device.

You’ll need to convert watts to amperes if you want to figure out how many amperes a smart TV uses in an hour. Because the power consumption of a smart TV is listed usually on the back in wattage. After that, divide the wattage by 1,000 to obtain the number of kWh that you’re utilizing each month.

If you wish to convert watts to amps, you’ll need to utilize the power formula, I = P / E, which stands for impulse power. Watts are represented by the letter P, whereas amps are represented by the letter I and volts are represented by the letter E.

What other factors affect your TV’s energy use?

You can anticipate a wide variety of energy usage across various television manufacturers and within their own product line of models. Take into account the age of your television as well. Since 2011, television makers have been obliged to include an Energy Guide label on their products. It helps consumers in understanding the energy usage of their televisions and other electrical home devices.

Older televisions, such as those with CRT displays, which are now considered outdated, use much more electricity than contemporary televisions with OLED screens of the same size.

While using the same technology, various TVs will draw varying numbers of amps depending on the technology used to create the display.

The advancement of technology has resulted in smart TVs that are becoming more energy efficient. The vast majority of the time, your amps will be less than one. In spite of this, it’s still essential to understand that kWh is the unit of measurement that will appear on your electricity bill. Then you can simply convert that number to amps just for fun.

Is the energy usage of all televisions the same?

No, the energy usage of various televisions varies. It is dependent on the display size and brightness settings, as well as the display technology used and the integration of services such as the Internet and Smart TV capability.

In a television, the screen uses the most power, not only because it is the biggest component, but also because it is responsible for the majority of the computation. This is why it has the biggest effect on power consumption.

Some Points to Keep in Mind

There are three things you should bear in mind while knowing How many amps does a TV use. First and foremost, the ampere figures are averages over a large number of different televisions, and their draws vary depending on the specific technology utilized for the panels.

The second point to mention is that both the brightness of your TV and the content shown on it can significantly reduce the number of electricity it consumes. For example, when a completely white image is shown on an OLED panel, the screen will pull its maximum amps. It is a much greater draw than when a totally black picture is displayed on the screen.

The third point is that you can always find out how many amps a particular television set consumes. It can be done when the brightness and sound are both set to their highest settings and the screen is consistently white. However, the average draw is much smaller and is dependent on the panel’s technology. As a result, even though OLED televisions have a greater maximum current draw than LED televisions, they are much more energy efficient.


Calculating the number of amps is a straightforward process that can be performed with any home device, not just your TV. And you don’t need to be a techie to be able to do that.

TVs are getting more energy-efficient as technology advances and advances. The most of the time, your amps will be less than one. So don’t worry about that much. You can easily know how many amps you will need.
