Why do lights dim if more lights or fans are turned on?
Homework Answers
It has to do with supply and demand. When the demand increases it can lower the relative supply. Imagine a hose with water flowing out the end. if you punch a bunch of holes in the hose the amount of water that reaches the end becomes less and less. If you put enough holes in the hose eventually you wont get any water coming out of the end of the hose. That is what has been happening in India with their power outages lately. Electrical Demand exceeded supply and the system became overloaded.
This is because the potentail difference across the bulbs lowers when other lights and fans ar eturned on.

6. People are driving through red lights with alarming frequency these days, but the police do not seem very invested in catching these drivers. In fact, the police spend more time going after speeders than trying to apprehend "red light runners," even though the latter are much more likely to cause a serious accident than the former. Using economic terms, tools, and concepts, suggest some possible explanations for the police behavior. Illustrate graphically.
