Powers Signs differ between sources and loads?

Alright, so my textbook specifically states that negative power indicates that power is being extracted from a device (I'm assuming they mean for loads) and then shows a negative power value at a current source as being power delivered. Is the sign…

Load Factor from max demand/time graph

I know Load factor is average demand/max demand so is this then LF= ((20x4)+(40x4)+(70x8)+(60x4)+(50x4))/70x24
