Unit of Power in SI Units is Watt

Power is defined as the rate of doing work or the rate of transfer of energy. The SI unit of power is the watt, which is defined as the amount of energy transferred or the work done in one second. The symbol for watt is W.

Explanation

The watt is named after James Watt, who was a Scottish inventor and mechanical engineer. He is known for his work on steam engines and was responsible for developing the Watt steam engine, which was a significant improvement over the Newcomen steam engine. The watt is defined as one joule per second, where a joule is the unit of energy and a second is the unit of time.

The watt is commonly used to express the power of electrical devices, such as light bulbs, motors, and generators. It is also used to describe the power output of engines, such as car engines and aircraft engines. In addition, the watt is used in the measurement of the power consumption of electronic devices, such as computers and televisions.

Conclusion

In conclusion, the unit of power in SI units is the watt, which is defined as the amount of energy transferred or the work done in one second. It is named after James Watt, who was a Scottish inventor and mechanical engineer. The watt is commonly used to express the power of electrical devices, engines, and electronic devices.
