As an expert in the field of electronics and home appliances, I can provide a comprehensive answer to your question about the electrical requirements for running a television.
Firstly, it's essential to understand the concept of amperage, which is a measure of electric current. It's one of the three primary components of electrical power, along with voltage and wattage. The amount of current a device uses, measured in amperes (amps), is determined by the power consumption of the device and the voltage supplied to it.
When considering the amperage required to run a television, several factors come into play:
1. Type of Television: The type of TV you have can significantly affect its power consumption. Older cathode ray tube (CRT) televisions, often referred to as "box TVs," were known to draw more current, often around 1 amp or more. However, modern televisions, such as LED (Light Emitting Diode) TVs, are much more energy efficient and consume less power.
2. Power Consumption: The power consumption of a TV, measured in watts, is a critical factor in determining the amperage it will draw. The formula to calculate the current (I) is given by Ohm's Law, which states \( I = \frac{P}{V} \), where \( P \) is the power in watts, and \( V \) is the voltage in volts. For example, a 100-watt TV operating on a 120-volt supply would draw \( \frac{100}{120} \approx 0.83 \) amps.
3. Energy Efficiency: Newer models of TVs are designed to be more energy efficient. LED TVs, for instance, consume significantly less power than their older counterparts. This efficiency not only reduces the amperage drawn but also lowers the overall electricity bill.
4. Screen Size and Resolution: Larger screen sizes and higher resolutions can lead to higher power consumption. However, the difference in amperage between different models can be quite small due to advancements in technology.
5. Additional Features: TVs with additional features such as built-in streaming services, smart capabilities, or high dynamic range (HDR) may consume slightly more power, but the difference is usually minimal.
6. Power Supply and Voltage: The power supply and voltage of your home or RV also play a role. In the United States, the standard voltage is 120 volts, while in many other countries, it's 220-240 volts. The voltage can affect the amperage drawn by the TV.
7.
Operational Mode: The TV's operational mode can also affect power consumption. For instance, a TV in standby mode consumes less power than when it's fully on.
8.
Other Appliances: It's also important to consider other appliances in your home or RV that may be drawing power. As you mentioned, devices like air conditioning units and microwaves can draw a significant amount of amps, which can affect the overall electrical load.
In conclusion, the amperage required to run a TV can vary widely depending on the type, model, and features of the TV, as well as the electrical system it's connected to. While older TVs might have drawn close to 1 amp, newer LED TVs likely consume less, possibly around 0.5 to 0.8 amps or even less, depending on the specific model and conditions.

A TV actually used less than 1 amp. 1 amp was the draw for the older box size TV's, but the newer LED TV's probably use less. Keep in mind that other accessories in your RV can pull a lot of amps, such as an AC unit and a Microwave. They are as high as 16 amps.Apr 19, 2016
