Question

give definition about power with so unit and dimension​

Answer 1

power is the rate of doing work

therefore p= W/t

where P= power

W= work done

and t= time taken to do that work

therefore the unit of power will be J/s

because the unit of work is J (joule) and time is seconds (s)

the dimensional formula for power

p= work/ time = [ ML^2T^-2] / [T]

p= [ML^2T^-3]
