Which of the following is analogous to the pipes in an electrical circuit?
large resistors causing restrictions to the flow of charge
capacitors storing the incoming charge from the battery
electric current flowing downhill" from the negative electrode to the positive electrode in a battery
electric current being forced uphill by the battery back to the positive terminal

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
