Power Triangle Formula Physics ~ Power is the rate at which work is done. The equation used to calculate the power is. Power is work or energy divided by time so power has the units of joules second which is called the watt a familiar term for just about anybody who uses anything electrical. Here is the equation that relates work done force applied and distance moved in the direction of the force. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. An average quantity in physics is often written with a bar over it as in the following equation for average power. As is implied by the equation for power a unit of power is equivalent to a unit of work divided by a unit of time. Mathematically it is computed using the following equation. We call this the power triangle. The formula for power is. Indeed recently has been sought by consumers around us, maybe one of you. People now are accustomed to using the internet in gadgets to view video and image information for inspiration, and according to the name of this post I will talk about about Power Triangle Formula Physics. Power is work or energy divided by time so power has the units of joules second which is called the watt a familiar term for just about anybody who uses anything electrical. The power dissipated by a load. The equation used to calculate the power is. The standard metric unit of power is the watt. Power p is measured in watts w. As these three elements are represented by a right angled triangle their relationship can be defined as. An average quantity in physics is often written with a bar over it as in the following equation for average power. W is measured in. Using the laws of trigonometry we can solve for the length of any side amount of any type of power given the lengths of the other two sides or the length of one side and an angle. In older works power is sometimes called activity.
For the potential energy the formula is. Mathematically it is computed using the following equation. In the international system of units the unit of power is the watt equal to one joule per second.
The standard metric unit of power is the watt.
It is the work time ratio. Power triangle is the representation of a right angle triangle showing the relation between active power reactive power and apparent power. S 2 p 2 q 2 where. Power can be defined as the rate at which work is done i e.
