The rating of a vacuum cleaner at 650 watts means that it has a power consumption of 650 watts when it is operating at its full capacity. In other words, the vacuum cleaner will consume 650 watts of electrical power every hour it is in use.
To calculate the total electrical energy consumed by the vacuum cleaner over 13 days of usage, let's break down the calculation step by step:
Find the daily energy consumption: Energy consumed in 1 hour = 650 watts Energy consumed in 1.5 hours (daily usage) = 650 watts * 1.5 hours = 975 watt-hours (Wh) or 0.975 kilowatt-hours (kWh)
Calculate the energy consumption over 13 days: Energy consumed in 1 day = 0.975 kWh Energy consumed in 13 days = 0.975 kWh * 13 days = 12.675 kWh
So, if the vacuum cleaner is used for 1.5 hours daily over 13 days, it will consume a total of 12.675 kilowatt-hours (kWh) of electrical energy. Please note that this is an estimate, and the actual energy consumption may vary slightly depending on the efficiency and performance of the vacuum cleaner.
