Series CombinationIf there was no R1 resistance then current I would not have been opposed by R1, that is almost 0 resistance would be on that particular spot.But now since R1 is present, the resistance at that place has increased from almost 0 to some greater value.According to Ohm's law, 1/I=R or if resistance increases, current would decrease.Thus the current passing through R2 resistance would be lesser than I, and the current passing through R3 resistance would be lesser than that passing through R2.But, why is it said that the same current(I) is passing through each of these three resistances.
