Answer:

Power is the amount of work that is done per unit of time. It can be associated with the speed of a change of energy within a system, or the time it takes to perform a job.

There are different types of power

Mechanical power: is that work performed by an individual or a machine in a certain period of time

Electric power: which is the result of the multiplication of the potential difference between the ends of a load and the current flowing there.

Mechanical power Formula


P=(W)/(t)\\ W=work\\t=time

Electric power Formula


P=V.I\\V=voltage\\I= current intensity
