How Many Amps Does a TV Use?

When buying a “blue screen” usually consider its capabilities and size, but not how much electricity it “takes. And in vain, because the figures can be quite impressive.

Television has been a staple of home entertainment for decades. Find out how many watts it costs to keep your TV and cut costs.

How Many Amps Does a Television Use?

In addition to ameres, there are other factors to consider when powering your TV. For example, a 50-inch TV with a good screen resolution requires 200 watts. This means that if you connect the TV to a 120-volt mains supply, it will need 1.6 amps. Conversely, if the TV requires 240 volts, the power consumption will be lower, or half that – 0.8 amps. This essentially means that at a higher voltage, the television needs fewer amps – one metre of current.

How Many Amps and watts Does a Smart TV Use?

A smart TV uses about 1 to 2 amps, depending on the model and brand. Most newer models use less energy than older models.

A smart TV uses about 60 watts of power, which is similar to a standard desktop computer. The power consumption will vary depending on the model and brand of TV. Some models may use more or less power.

How to Calculate Amps

To calculate the amps for an electrical circuit, you need to know the voltage of the circuit and the resistance of the circuit. The formula for calculating amps is:

Amps = Voltage / Resistance

For example, if you have a circuit with a voltage of 12 volts and a resistance of 4 ohms, the calculation would be:

Amps = 12 volts / 4 ohms

This would give you a result of 3 amps.

Measuring your TV’s electricity consumption

You can measure for yourself the amount of electricity you use. It is a time-consuming but interesting and very efficient process. To do this, you will need an instantaneous power meter – a wattmeter. The best option is a domestic, local one, which you plug into a wall socket. It will measure and remember the power, and some models will even help you calculate the cost of electricity at a given price.

If you don’t want to bother, you can just open a book with the specifications of a particular model. Manufacturers always state how much electricity your TV consumes at maximum power and in standby mode. The amount of the electricity bill depends on the type of TV receiver and the length of time it is on. The approximate time a person watches TV is 5 hours a day, for 30 days 150 hours. Let’s look at the different options.

Televisions with cathode ray tube.

These are the well-known bulky cinema models. Their advantages include their extremely long life, which is why they still exist in some households. But such receivers cannot be very economical. They consume between 60 and 100 watts per hour. This means that in the worst case we can consume 0.5 kW in one day. One month of watching TV would give us 15 kW. Add to that a consumption of 2-3 watts per hour in standby mode around the clock. Total 16.44-17.16 kW per month.

LCD and LED TVs

Liquid crystal panels are gradually disappearing from the market, but they have not yet fully surrendered their positions. How much electricity an LCD TV consumes depends on the size of the screen. A small screen up to 32 inches consumes an average of 40-55 watts per hour and 1 watt in standby mode. Thus, one month’s power will amount to 6.72-8.97 watts. LED panels are essentially a modern subspecies of LCD, which consume about 40% less power. The standby mode is 0.3W in most cases. A fairly large 49″ monitor consumes 100-150 watts/hour. Total: 15.22-22.72 kWh/month.

How many watts and amps do plasma screens consume Plasma TVs are considered by some to be the pinnacle of technology: high quality color reproduction, saturated picture. Unfortunately, however, these models cannot boast of their energy efficiency. A modern panel with a diagonal of more than 42 inches consumes around 150-190 W per hour and 0.5 W in standby mode. It is not difficult to calculate how much electricity such a TV requires per month 24,36-28,86 kW. The advantage is that different pictures can consume different amounts of electricity, but manufacturers specify a maximum.

Environmental friendliness and eco-friendliness

Knowing how much electricity your TV consumes not only helps you save money, but you can also help protect the global environment. Around the world, new energy standards are being set and manufacturers are working to meet them. So before you buy a receiver, it’s worth finding out about the eco-friendly features of your chosen model.

Consumption category

The most energy efficient televisions are labelled with the highest energy efficiency class, A. However, many other home appliances have long been rated A+, A++, A+++. The more pluses, the lower the consumption. From 1 January 2017, televisions will also carry an A++ sticker and from 1 January 2020 A+++. In other words, according to the European Commission, there will be new, energy-efficient models as early as next year.

Eco-modes

Most modern televisions have eco-modes. Their essence is to reduce the unnecessary brightness of the picture. The settings can be optimised according to lighting conditions, either manually or automatically. The latter is possible thanks to special sensors that analyse the environment.

Presence detectors

The function of turning off unused TV is quite common, but occupancy sensors are quite an interesting novelty. They recognize the movements of bodies and faces sitting in front of the screen. If no viewers are detected, the picture turns off.

Tips for saving money

Install the unit in a place with even lighting. Then the brightness and contrast settings can be set to minimum, which will save up to 5% electricity.

Standby mode is called “vampire” mode. The above calculates how much electricity the TV consumes when it is not performing its primary function. Unplug the device from the power outlet.

If your model has eco-functions, use them.
