Question
A lamp transfers 54 KJ of energy.
Calculate the power of this lamp if it is used for 1 hour.
Power = _____ W
0.0151590054 000
Solution
To calculate the power of the lamp, we need to use the formula for power which is:
Power = Energy / Time
The energy transferred by the lamp is given as 54 KJ (Kilojoules). We need to convert this to Joules because the standard unit of energy in the formula is Joules.
1 KJ = 1000 Joules
So, 54 KJ = 54,000 Joules
The time is given as 1 hour. We need to convert this to seconds because the standard unit of time in the formula is seconds.
1 hour = 3600 seconds
Now we can substitute these values into the formula:
Power = 54,000 Joules / 3600 seconds = 15 Watts
So, the power of the lamp is 15 Watts.
