Question

Сколько расходуется электричество энергосберегательной лампочки мощностью 250ВТ за 5 часов

Answer 1

0.25 кВт за час своей работы.
0,25*5=1,25 кВт/час

Answer 2

Calculating Electricity Consumption of a 250W Energy-Saving Light Bulb

To calculate the electricity consumption of an energy-saving light bulb with a power rating of 250W over a period of 5 hours, we can use the formula:

Electricity Consumption (kWh) = Power (kW) × Time (h)

Given: - Power (P) = 250W = 0.25kW - Time (t) = 5 hours

Using the formula, we can calculate the electricity consumption:

Electricity Consumption (kWh) = 0.25 kW × 5 h = 1.25 kWh

So, the electricity consumption of a 250W energy-saving light bulb over 5 hours is 1.25 kWh.
