A certain number of identical resistors are connected in series and their total resistance is measured. When the resistors are disconnected and re-connected in parallel, their total resistance drops to one-percent of the value measured when they were connected in series. How many resistors are there?
For this question, I know the answer. What I need help with is finding assumptions and/or simplifications:
Determine which physics concepts and/or laws are involved and what assumptions and/or simplifications can be made about the physical situation in order to apply them. What simplifications are reasonable? The assumptions which simplify the problem must be explicitly stated and consistent with the applicable concepts. For example, if momentum conservation is being applied to a system of two cars in a collision, then friction from the road will be ignored since it is an external force and the system has been simplified to have no external forces in order to apply the conservation law.
