Question

si unit of power???????​

Answer 1

Answer:

The S.I. unit of power is watt. James Watt was an inventor and mechanical engineer. He measured the power of a horse (standard one) by observing how much load it can pull within unit time. To honor him we take the name to use as unit of power.

Power, P = W/t

here, W stands for Work and t for time.

The amount of work by any system in unit time is called it's power.

The unit of work or energy is joule (to honor James Prescott Joule) and unit of time is second.

So, 1 joule per second equal 1 watt.

Answer 2

Answer:

• SI unit of power is Watt ( j/s or W )

Fundamental Units

There are some quantities which are not related to one another and cannot be expressed using other quantities. Such Quantities are fundamental quantities. The units of the fundamental quantities are the fundamental Units. The system based on these fundamental Units is the International System of Units. It's short form is SI units.

Some fundamental Quantities and their SI units :

• Length - m ( metre )

• Mass - kg ( Kilogram )

• Time - s ( second )

• Electric Current - A ( Ampere )

• Temperature - K ( Kelvin ).

• Amount of Substance - mol ( mole )

• Luminous Intensity - cd ( candela )
