This video about Stand Fan Energy Saving Tips | How much electricity does your fan use

Fan power consumption is based on the mode in which the fan operates. Usually fans have 3 to 4 speeds that determine the power consumption of the fan.

The power consumption of a table fan depends on several factors, including its wattage, the speed at which it's running, and the efficiency of the motor. Here's how you can calculate or estimate the power consumption of a table fan:

1. Wattage Rating: Most table fans have a wattage rating mentioned on their packaging or user manual. This wattage rating indicates the maximum power the fan will consume when running at its highest speed. For example, if the fan is rated at 50 watts, it will consume 50 watts when running at its maximum speed.

2. Speed Settings: Many table fans come with multiple speed settings, such as low, medium, and high. The power consumption will vary depending on the speed at which the fan is running. Typically, the higher the speed, the more power the fan will consume.

3. Formula: To calculate the power consumption of the fan at a specific speed, you can use the formula:

Power Consumption (W) = Fan's Wattage (W) x Speed Setting (%)

For example, if the fan is rated at 50 watts and you're running it at 50% speed:

Power Consumption = 50 W x 0.5 = 25 W

Remember that this formula provides an estimate. Actual power consumption might vary based on factors like the fan's design, motor efficiency, and the quality of components used.

Keep in mind that leaving a fan running for a long time will accumulate power consumption. To determine the energy cost of running the fan, you'll need to multiply the power consumption by the number of hours the fan is operating and the cost of electricity per kilowatt-hour (kWh) in your area. The formula for calculating energy cost is:

Energy Cost ($) = Power Consumption (kW) x Hours of Operation x Cost of Electricity (per kWh)

To summarize, the power consumption of a table fan depends on its wattage, speed setting, and the duration it's running. Check the fan's wattage rating and use the formula provided to estimate power consumption.
