Frequently asked questions
- What is the difference between power and energy?
- Energy (J) is the total amount of work done; power (W) is how fast it is done. A 100 W bulb running for 36,000 s uses 3,600,000 J = 1 kWh.
- How do I convert watts to horsepower?
- Divide watts by 745.7. A 1000 W motor produces about 1.34 hp.
