Here P stands for power, V stands for potential difference and I stands for Current. This states that power is directly proportional to the potential difference of the conductor. The formula is given by a great scientist named Ohm, and this formula is named after him and is also known as ohm's law. This formula for power is taken from the electricity chapter. The Power Formula for Different Relations and Units are: Power formula differs as per the required statements, for example, it can be different for force-related objects and also can differ for electronic devices. Power = Work done by the object or body / Total time taken. This is exactly what power is, it is defined as the work done by a body in the given time. It simply means that A is more efficient than B and the efficiency is directly proportional to Power hence we can say that A is more powerful than B. Let's suppose A and B are two people doing the same task but A finished the task before B then what does it mean? The powder formula can be defined as the work done by any specific object or source per given time. The main agenda remains the same, which is the ability to do work at a particular time. This power can be anything either in the form of electricity, physical, human resources, etc. If we look around ourselves we'll find several things that require power to run or work.
POWER EQUATION MAKER PDF
There are many more power formulas that you can easily find in the PDF File that Vedantu provides for free. This formula states that power is the consumption of energy per unit of time. The formula is P = E/t, where P means power, E means energy, and t means time in seconds. There is yet another formula, which is called mechanical power equation, or simply power equation. Here, R is for Resistance, V is for potential difference, and l is for current. Ohm’s law also has a variant, which goes like P = r × l2 or V2/ R, this is the formula for the electric power. In the formula, P = VI, p stands for power, V stands for potential difference, and I stands for current. The formula goes P = VI, and it is given in the electricity chapter of the book. There is one formula of the power called “Ohm’s law”, named after the scientist who gave this formula. This is the general idea of power, there are many instances in which the power formula changes. In simple terms, the power of anything can be obtained from dividing the work that the object has done by the time the object has taken to do that work. And with the knowledge of the work efficiency of someone or something, we can also make some good judgments and decisions regarding the same. It is simply because x has more power than y.įrom the given example it can also be understood how the power can help in determining how much work is done, and at what time it has been done. It means that the “x” is more efficient than the “y”. For instance, if x and y are doing the same task and x completes in 4 hours, while y completes the same task in 6 hours. It helps in determining which object is more efficient and which object is less efficient. The power formula helps in determining the work done by a particular object or a person at a particular time. The power formula serves many purposes, such as: Also, this power can be in some other form as well, such as physical, or human resources. Hence, electricity is the power for such devices. Similarly, if there is no electricity in the home, the fan cannot work. For instance, many devices such as mobile phones, computers, fans, etc work on electricity, if we do not charge the battery of our phone, then it is going to be switched off.
Here, the word power is used to address anything which provides the necessary force or the energy to the thing to work properly. Most of the things around us require some power for working efficiently.
