What is Power?

Power is the rate of doing work. The unit of power is the watt (W). Power equals work over time, P = W/t or P = F x d.

◉ Power is a scalar quantity

Formula of power

Power = Watt / time = W / t

Units of power

SI units of power are J/s or watt, but also kilowatt, megawatt, and house power

What is watt

Watt is a derived unit of power in the International System of Units (SI) and is defined as a derived unit of power in the International System of Units (SI). The unit is named after James Watt. The watt is defined as one joule per second and can be used to quantify the rate of energy transfer.

What is house power

A horsepower is a unit of measurement of the rate at which work is done. It is defined as the rate of energy expenditure per unit of time and is equivalent to one horsepower for a rate of one hour per hour. It was originally defined as the amount of work done by a horse in one minute but is now defined as exactly 745.7 watts. To calculate the horsepower of a car, you multiply the number of cylinders in the engine times the number of pistons in the engine times the number of revolutions the engine can make per minute. Horsepower is often shortened to HP.
