Question

define power and what is the SI unit​

Answer 1

Answer:

Power is defined as the rate of doing work or rate of consumption of energy. Power is calculated by P=tE. 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 Secjoule.

Answer 2

Explanation:

Power (P) is the rate at which energy is transferred or converted .

Thus, power equals work divided by time (P = W / t) .

The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 - 1819).

One watt equals one joule per second (W = J / s).
