W
Energy is measured in Joules(J). Power is measured in Watts(W). 1 W = 1 J/Second. Power is the rate at which energy is delivered.
Watt [W]. One watt is 1 W = 1 J / s [joule/second].
dB = 10 log(power-2/power-1) = 10 log(80) = 19.03 dB

11 KW = 11 000 W 1 W = 1 J / s (1 Joule pr second). 11000 W = 11000 J/s
1 w
The SI unit for power, thermal or mechanical, is the watt, W. 1 W = 1 J/s (joule/second).
power=workdone/timetaken or p=w/t
W is short for watt, which is a unit of power. 1 watt is the same as 1 joule/second.
W to the rd power is the same as W raised to the power of r times d, or (W^r)^d.
Power is the rate of flow or usage of energy. 1 Watt = 1 Joule per second
