Answer:
The amount of power in kilowatt hour consumed by the the bathroom lights in 1 year is 438 kWh
Step-by-step explanation:
The given parameters are;
The number of bulbs in the bathroom = 8
The power rating of each bulb = 75 W
The number of hours each bulb is lit on daily = 2 hours
The number of days in a year for which the kWh is sought = 365 days
The watt hour consumed by the the bathroom bulb in 1 year = 8 × 75 ×2 × 365 = 438,000 wh
The watt hour consumed by the the bathroom bulb in 1 year = 438,000 wh.
Now you have to convert to kWh which is 438,000/1,000
The kWh used per year by the bathroom bulbs is 438 kWh.
(I just used the other person's work, but they forgot to convert wh to kWh)
