Question

find the dimensional formula for power

Answer 1

Common symbols

P

SI unit

watt (W)

In SI base units

kg⋅m2⋅s−3

Derivations from

other quantities

P = E/t

P = F·v

P = V·I

P = T·ω

dimensional formula of power is given by,

M1 L2 T-3

Where,

M = Mass

L = Length

T = Time

Derivation

Power (P) = Work × time-1 = Joule × second-1 . . . . . (1)

Since, Work (J) = N × m = M1 L1 T-2 × [L]

Therefore, the dimensional formula of work = M1 L2 T-2 . . . . (2)

On substituting equation (2) in equation (1) we get,

Power (P) = Work × time-1

Or, P = [M1 L2 T-2] × [T-1] = M1 L2 T-3.

Therefore, power is dimensionally represented as M1 L2 T-3.

Answer 2

Answer:

⭕..#@ÑSWER......

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second.
