To convert watts to kilowatt-hours (kWh), you need to divide the wattage by 1000. In this case, 550 watts is equal to 0.55 kilowatt-hours (550 / 1000 = 0.55 kWh).

How many kw consumption does a 20w bulb consume in 24 hours?

A 20-watt bulb consumes 20 watts of power. To calculate its consumption over 24 hours, multiply the wattage by the number of hours: 20 watts × 24 hours = 480 watt-hours. To convert watt-hours to kilowatt-hours (kWh), divide by 1,000: 480 watt-hours ÷ 1,000 = 0.48 kWh. Therefore, a 20-watt bulb consumes 0.48 kWh in 24 hours.

What is the total kilowatt hours used if a microwave oven operates on 5 amperes of current on a 110-volts circuit for one hour?

Power = (voltage) x (current) = 110 x 5 = 550 wattsIf operated at this level for 1 hour, thenEnergy = (550 watts) x (1 hour) = 550 watt-hours = 0.55 kilowatt-hour.Another AnswerAs microwave ovens don't operate continuously, but in short bursts, it's not really possible to determine an answer to your question without knowing the frequency and duration of these bursts of energy.


How do you convert 665 kWh to calories?

A watt is a J/s. So a kWh is 1000 (J * hr)/s. Since there are 3600 seconds in an hour: 1 kWh = 3,600,000 J. There are 4.18 J per calorie, so: 1 kWh = 861,000 cal 665 kWh = 573,000,000 cal
