Answer 1

Answer:

Define what is means by the term of power and it's SI unit?

Explanation:

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. ... The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft.

SI unit: watt (W)

In SI base units: kg⋅m2⋅s−3

Answer 2

Power is defined as the rate of doing work or rate of consumption of energy.

Power is calculated by P=

t

E

where E is the energy consumed.

Unit of energy or work done is Joule (J) and time is Second

So unit of Power will be

Sec

joule

It is given as : SI unit of power is Watt denoted by W.
