Have you ever wondered how many amps does a 40 Inch TV Use?TVs have a long time ago became a commonplace sight in our homes, today it is practically impossible to imagine a dwelling without at least one.Even mobile homes such as campers and RVs have them as a part of standard equipment, along with stoves and fridges.We get our news and entertainment from them, which why TVs are widely regarded as the essential pieces of electronic equipment.Whether you are camping, living off the grid, or building a vehicle for outdoor activities, how much amps your TV is drawing can be an important thing to know.So, how many amps does a 40 Inch TV Use? Depending on the technology of the screen, a 40-inch TV will use the following amps:A 40 Inch plasma TV would use on average 1,67 ampsA 40 Inch LCD TV will use 0.83 ampsA 40 Inch LED TV will use 0.42 ampsA 40 Inch OLED will use 0.6 amps

How Many Amps Does A 40-inch TV Use?
The amp draw of any electric or electronic device depends on many things, when it comes to TV sets, it is primarily the size and technology of its screen.Older TVs such as those with, these days obsolete, CRT screen have much higher power draw than modern TVs with OLED screens of the same size.At the same time, TVs with the same technology will pull the different amounts of amps depending on the technology of the screen.

The screen of a TV is the part that consumes the most power, not just because it is the largest part but also because it does the most of the work. This is the reason why it has the greatest impact on power draw.Depending on the technology of the screen, a 40-inch TV can draw different amounts of amps. For example, an old plasma TV would on average have a maximum draw of 1,67 amps, while an LCD TV of the same size on average has a maximum draw half of that, 0.83 amps.The two most common TV types today are LED and OLED panels. On average, an LED TV with a 40-inch panel will have a maximum draw of 0.42 amps, while an OLED of the same size will have a slightly higher maximum draw of 0.6 amps.There are three things you should keep in mind. First, that these numbers are averages between many different TVs and that depending on the exact technology used for panels their draws vary.For example, LG and Samsung use different LEDs for their TV backlight and though technically they both make LED TVs their draws differ slightly.Second thing is that both brightness and what is on your screen can substantially decrease how many amps your TV is drawing. For example, an OLED screen will draw its maximum amps when the screen is a uniformly white picture, which is a substantially higher draw than in the case of a uniformly black screen.Third thing is that you can always find out the maximum amps draw of some TV set, which is when brightness and sound are set to maximum and show a uniformly white screen.But the typical draw is much lower and depends on the technology of the panel. That’s why OLED TVs, though they have a higher maximum draw than LED ones, actually are much more energy efficient.

How To Find Out How Many Amps A TV Draws?
Very rarely you will find out how many amps some TV draws. It is a type of information an average consumer doesn’t really need, so it isn’t provided on the specs sheet. But you can easily calculate it.For almost any TV set you can find on its spec sheet what is its maximum power draw or consumption in watts. To find out the maximum amperage draw all you need to is divide this number with the nominal voltage such a TV set is intended to work on.But keep in mind, while the American household power grid is called 110V, it’s actually working on 120V.So for example some typical 40-inch OLED TV could have a maximum power draw of 72 watts. Divide by 120 volts, it gives 0.6 amps.Some TV sets on the other hand only have a product energy guide that states estimated annual power consumption in kilowatts hours, with a small print stating that it is based on a 5-hours per day use, or something similar.Calculating amperage from this number is also very easy, all you need to know is that a kilowatt-hour (kWh) is a thousand watt-hours.
And that for example, a device that draws 100 watts, during one hour will consume 100 watt-hours, over two hours will consume 200 watt-hours.Watt-hours is just the multiplication of the device’s wattage and the number of hours they are working.So for example, for a TV set that has a 92 kWh consumption estimate based on 5 hours per day use, you would go about calculating by first dividing 92,000 with 364 to get the daily consumption. In this case, it is 252.75 Wh.Dividing this number with 5 you will get consumption per hour of 50.55 Wh, in other words, 50.55 watts rating.Dividing 50.55 watts with nominal 120 volts will tell you that this TV set typically draws just 0.42 amps.
What Are Amps?
Ampere or for a short amp is a unit for measuring the electrical current. The easiest way to understand what this actually means is to use the water analogy because after all, electricity is a flow in a sense.If you think about an electric wire as a water hose, amps are equivalent to gallons of water flowing through it per second.Volts, Amps, and Watts Explained >> Check out the video below:
Just as through a hose of a certain radius water can flow at different rates up to a maximum before such hose bursts open, electric wires can withstand currents up to a certain amount that depends on their radius, or gauge.If the current exceeds the limit of some wire, it will burst in flames so to speak.Determining how much a 40-inch TV set draw amps have many applications. The home environments tell us how thick or thin wires we can use for electrical installation.But when using a TV in the off-the-grid setting and powering it with a battery it can tell you for how long you can use a TV set with a certain battery.The battery capacity is often expressed in milliamp-hours or amp-hours. So dividing this number with the maximum amperage of a TV set will give you the minimum amount hours it can run on that battery.Referenceshttps://www.deepcyclemarinebattery.com/articles/tv-wattage-how-many-watts-and-amps-does-a-tv-use.htmlhttps://understandsolar.com/how-many-watts-does-a-tv-use/Love It?
