A 25h electric lamp consumes 1kW * h. what is the power of this lamp? What does 25h mean
It is known that w = 1kW. H t = 25h according to the formula w = Pt
So p = w / T = 1 / 25 kW = 0.04kw = 40W
T = 25h is the time of 25 hours
A lamp consumes 1kW · h for 25h. What is the power of this lamp?
The power of this lamp: P = wt = 1kW · h25h = 0.04kw = 40W. A: the power of this lamp is 40W
