Ramu and Raju are dragging water in a bucket from the wells A and B respectively. Ramu dragged three buckets of water within 5 minutes but Raju could not do for the short interval of time. He could take only two buckets of water in 7 minutes. What do you inter from this Incidence.
What is the expression and unit for power ?

From the incident, it is known that Ramu has got more power than Raju. Because Ramu dragged (lifted) 3 buckets within 5 minutes So he had done more work in a short interval of time, but Raju did not do it. According to definition of power, rate at which work is done, is power for shorter period of time, if work done is more, then power is also more.
Rate of doing work (or) Rate at which work is done is Power.
(P) Power `=("Work")/("time")=(W)/(t)`
Work (Energy) = Power `xx` time
`W=P xx t`
Unit of power is watt (W)
Unit of Energy is wat second (joule).
