Power vs Time
सूत्र
## Mechanical Power Power is the rate at which work is performed or energy is transferred. ### Formula **P = W / t** One watt equals one joule per second. To convert watts to horsepower, divide by 745.7.
हल किया गया उदाहरण
A motor does 1000 J of work in 5 seconds.
- 01P = W / t
- 02P = 1000 / 5
- 03P = 200 W
- 04P = 0.2 kW
- 05P = 200 / 745.7 = 0.268 hp
अक्सर पूछे जाने वाले प्रश्न
What is the difference between power and energy?
Energy is the total amount of work done, while power is the rate at which that work is done. A 100 W bulb uses 100 joules of energy every second.
How do you convert watts to horsepower?
Divide watts by 745.7 to get mechanical horsepower. For example, 746 W is approximately 1 hp.
What is a kilowatt-hour?
A kilowatt-hour (kWh) is a unit of energy equal to 1000 watts sustained for one hour, or 3,600,000 joules.
