# What is the Dimensional Formula of Power?

Posted in Dimensional Formulae | Email This Post |Power is defined as work done per unit time. Its formula is

**Power= Work/Time**

Dimensional Formula of Work= M^{1}L^{2}T^{-2} Divide it by Time T^{1}

**So Dimensional Formula of Power= M ^{1}L^{2}T^{-3}**

**SI unit of Power is Watt represented by W**

good…………………

vry nice

superb

Thanx.. Nice post.

good thanks for that formula

thnks for the formula but you must explain it a bit

thanksssssssssssss

Fantastic!

very very very helpful site for our improvement

Awesome

I have a question regarding this, above mentioned your final answer is M1L2T-3 but this is not in below choices. Can you please make sure either is it correct or not?

The dimensions of power are:

(a) ML2T-2 (b) ML 2T2

(c) ML 2T-1 (d) ML -1T-1

hi,

none of this is correct.please see the derivation above.

thank u

Very very helpful

Very nice;)

Thx

thx
