The number of watts a TV uses can vary significantly depending on factors such as the type of TV, its size, and its age. Here's a general overview of power consumption for different types of TVs: Modern LED TVs: Between 30 to 100 watts, depending on the screen size. LCD TVs: Approximately 50 to 200 watts. Plasma TVs: Around 100 to 400 watts. It's important to note that these are approximate figures, and individual TV models may have slightly different power consumption rates. Additionally, TVs consume a small amount of power (typically 0.5 to 3 watts) while in standby mode. To determine the exact wattage of your TV, you can refer to the user manual or the label on the back of the device, which usually provides the required information.
