Question

Электроплитка мощностью 800 включена на 5 часов . Определите расход энергии( в ватт-часах и киловатт-часах)

Answer 1

4000 т ватт или 4 киловатта

Answer 2

Calculation of Energy Consumption

To determine the energy consumption of an electric stove with a power of 800 watts that is turned on for 5 hours, we can use the formula:

Energy Consumption (in watt-hours) = Power (in watts) x Time (in hours)

Given that the power of the electric stove is 800 watts and it is turned on for 5 hours, we can calculate the energy consumption as follows:

Energy Consumption (in watt-hours) = 800 watts x 5 hours = 4000 watt-hours

To convert watt-hours to kilowatt-hours, we can divide the energy consumption by 1000:

Energy Consumption (in kilowatt-hours) = 4000 watt-hours / 1000 = 4 kilowatt-hours

Therefore, the energy consumption of the electric stove with a power of 800 watts, when turned on for 5 hours, is 4000 watt-hours or 4 kilowatt-hours.
