HOW TO CALCULATE THE DIMENSIONS OF POWER?



Power can be defined as the work done per unit time.

Mathematically, 


\[POWER=\frac{WORK DONE}{TIME}\]

The work done is a product of force acting on a body and the its displacement. 

\[POWER=\frac{FORCE* DISPLACEMENT}{TIME}\]

\[P=\frac{F*s}{t}\]

Therefore the dimensions of the power can be given as,

\[[P]=\frac{[F]*[s]}{[t]}\]

as we know that,

the dimensions of the force is 

\[[F]=[M^{1},L^{1},T^{-2}]\]

Therefore,

\[[P]=\frac{[M^{1},L^{1},T^{-2}]*[L]^{1}}{[T]^{1}}\]

\[[P]=[M^{1},L^{1},T^{-2}]*[L]^{1}*[T]^{-1}\]

\[[P]=[M^{1},L^{1+1},T^{-2-1}]\]

The dimensions of the power can be given as, 

\[[P]=[M^{1},L^{2},T^{-3}]\]

In a potentiometer circuit, a cell of EMF 1.5 V gives a balance point at 36 cm length of wire. If another cell of EMF 2.5 V replaces the first cell, then at what length of the wire, does the balance point occur?
