Question
A lamp transfers 108 kJ of energy.Calculate the power of this lamp if it is used for 1 hour.Power = _____ W1800300.03108 000
Solution
To calculate the power of the lamp, you need to know the formula for power. The formula for power (P) is:
P = Energy (E) / Time (T)
The energy is given as 108 kJ, but power is typically measured in watts (W), and 1 W is equal to 1 joule/second. So, we need to convert the energy from kJ to joules.
1 kJ = 1000 joules
So, 108 kJ = 108,000 joules
The time is given as 1 hour. We need to convert this to seconds because the standard unit of time in this context is the second.
1 hour = 3600 seconds
Now we can substitute these values into the formula:
P = 108,000 joules / 3600 seconds = 30 W
So, the power of the lamp is 30 watts.
