Witryna1 mar 2024 · 3 bulbs x 20W (each) = 60W. But, since you have four bulbs, then the load connected is equivalent to: 4 bulbs x 20W (each) = 80W. Thus, the Demand Factor would be (0.6) by applying the formula of demand factor. If you want to calculate the D f in terms of (%) percentage, then you can multiply the outcome by 120W. So, 0.6 x 80 … Witryna2 maj 2000 · Abstract.
