An electric lamp of 100w is used for 5 hours per day calculate the uni...
Given:
- Power of the electric lamp = 100W
- Time the lamp is used = 5 hours per day
To find:
- Units of energy consumed by the lamp in one day
Solution:
The energy consumed by an electrical appliance can be calculated using the formula:
Energy (in kilowatt-hours) = Power (in kilowatts) x Time (in hours)
Converting the power from watts to kilowatts:
1 kilowatt = 1000 watts
So, the power of the lamp in kilowatts = 100W / 1000 = 0.1kW
Calculating the energy consumed:
Energy (in kilowatt-hours) = Power (in kilowatts) x Time (in hours)
Energy = 0.1kW x 5 hours = 0.5 kilowatt-hours
Converting kilowatt-hours to units:
1 unit = 1 kilowatt-hour
Therefore, the energy consumed by the lamp in one day is 0.5 units.
Answer:
- The units of energy consumed by the lamp in one day is 0.5 units.
- Power of the electric lamp = 100W
- Time the lamp is used = 5 hours per day
To find:
- Units of energy consumed by the lamp in one day
Solution:
The energy consumed by an electrical appliance can be calculated using the formula:
Energy (in kilowatt-hours) = Power (in kilowatts) x Time (in hours)
Converting the power from watts to kilowatts:
1 kilowatt = 1000 watts
So, the power of the lamp in kilowatts = 100W / 1000 = 0.1kW
Calculating the energy consumed:
Energy (in kilowatt-hours) = Power (in kilowatts) x Time (in hours)
Energy = 0.1kW x 5 hours = 0.5 kilowatt-hours
Converting kilowatt-hours to units:
1 unit = 1 kilowatt-hour
Therefore, the energy consumed by the lamp in one day is 0.5 units.
Answer:
- The units of energy consumed by the lamp in one day is 0.5 units.
