The power of the fan is 70 Watt.
What is power?
Power can be defined as the rate at which energy is used. The S.I unit of power is Watt (W)
The power of the fan can be calculated using the formula below.
Formula:
- P = E/t.......................... Eqaution 1
Where:
- P = Power of the fan
- E = Energy of the fan
- t = time
From the question,
Given:
- E = 4.2 kJ = 4200 J
- t = 1 minutes = 60 seconds.
Substitute these values into equation 1
Hence, The power of the fan is 70 Watt.
