How much energy in kilowatt hour is consumed in operating ten 50 watt bulbs for 10 hours per day in a month (30 days
Question
How much energy in kilowatt hour is consumed in operating ten 50 watt bulbs for 10 hours per day in a month (30 days
Solution
Sure, let's break it down:
-
First, we need to find out how much energy a single bulb consumes in a day. Since the power of the bulb is given in watts, we need to convert it to kilowatts because the energy is required in kilowatt-hours. 1 kilowatt is equal to 1000 watts. So, 50 watts = 50/1000 = 0.05 kilowatts.
-
Next, we calculate the energy consumed by one bulb in a day. Energy is power multiplied by time. So, the energy consumed by one bulb in a day is 0.05 kilowatts * 10 hours = 0.5 kilowatt-hours.
-
Now, we calculate the energy consumed by one bulb in a month. Since a month is considered to have 30 days, the energy consumed by one bulb in a month is 0.5 kilowatt-hours/day * 30 days = 15 kilowatt-hours.
-
Finally, since there are 10 bulbs, the total energy consumed by ten 50 watt bulbs in a month is 15 kilowatt-hours/bulb * 10 bulbs = 150 kilowatt-hours.
