First Class Formula For Power Output Physics
Power is the rate at which work is done.
Formula for power output physics. Force mass acceleration due to gravity for vertical motion by replacing Work in the formula of power by m g h we get. It states that the total time taken by an object to displace from one place to another when an external force is applied to it is called power. In regard to Voltage and current it is articulated as.
Efficiency frac usefulpowertransferred totalpowersupplied. First take the 25 x 106cal and convert to Joules using the conversion factor 418 J cal. Power Power is the rate at which work is done.
In this formula F denotes force applied In the object s denotes displacement of the object and t denotes the total time taken. P F st. Figuring out our average power output we simply divide the energy by the number of seconds in a day 86400 which gives a bit more than 100 W.
It is the worktime ratio. Power Work time or P W t. The practical unit of power is kilowatt and horse power.
Power Work time and Work Force distance the body is moved Force mass acceleration of the body. Where 1 kilowatt 100 watt and 1 HP 746 watt. This gives roughly 1 x 107J.
The symbol for current is I it is measured in Amperes. Since we are given the amount of time in the question stem well need to find a way to calculate. In any electrical circuit the power is computed making use of these three formulas.
