Answer :
Final answer:
The 100 W bulb will consume 30,000 watt-hours (Wh) or 30 kilowatt-hours (kWh) of energy in 30 days when used for 10 hours every day.
Explanation:
To calculate the energy consumption of a 100 W bulb over 30 days when used for 10 hours each day, we can use the formula:
Energy (kWh) = Power (kW) × Time (hours)
First, we need to convert the power of the bulb from watts (W) to kilowatts (kW):
Power (kW) = 100 W ÷ 1000 = 0.1 kW
Now, we can calculate the energy consumption:
Energy (kWh) = 0.1 kW × 10 hours/day × 30 days = 30 kWh
So, the 100 W bulb will consume 30,000 watt-hours (Wh) or 30 kilowatt-hours (kWh) of energy in 30 days when used for 10 hours every day.
