Question

What is power and efficiency of power

Answer 1

Hyy dear here is your answer

Normal power means the ability to control people or things to do something.

And an Electrical power is the rate at which electrical energy is converted to another form, such as motion, heat, or an electromagnetic field.

Efficiency is the ratio of total output power to input power, expressed in percent. This is normally specified at full load and nominal input voltage. Power supply efficiency is the amount of the actual power delivered to the components divided by the electrical power drawn from the mains supply socket.
