Matchless What Is The Dimensional Formula Of Power
Also know what is power and work.
What is the dimensional formula of power. So it is a expression and it is called dimensional formula. A Name the principle used. One common unit of energy is the kilowatt-hour kWh.
Dimension formula of mass is. Must be raised to represent it or the dimension of the units of a derived physical quantity is. Power P M1 L2 T-3 Density D.
For example dimensional force is F M L T-2 Its because the unit of Force is Netwon or kgms2. To break this down a Watt is a unit of power ie energy transfer per second is Joules per second. Power is the work done in a unit of time.
If Q is any physical quantity the expression representing its dimensional formula is given by. The SI unit of electric power is the watt W. PowerWorktime Pwt DEFINITION NO.
If you master it you will never get lost in complicated problems with lots of dimensions. So Dimensional Formula of Power M1L2T-3. Power P Work time -1 Joule second -1.
As highlighted earlier one of the advantages of dimensional formulas is the ability to check for dimensional correctness in formulas. Other useful dimensional formulas and their equations include. A watt hour is a measure of energy so its SI dimensions are Joules.
