Question

Why would the current be 0 through lamp C when the switch is connected? According to my textbook "Current Does Not Take the Path of Least Resistance". The current takes all paths. Those paths with lower resistance [like that path with the switch] will have large currents, but even very high-resistance paths [like the path with bulb C] will carry some current. According to this, the answer give would be wrong. And say that the current does take the path of least resistance, as suggested by the answer to question 29, then there would always only be one loop in a circuit- the loop of least resistance. 

Explanation / Answer

   The statement given in text book is an exactstatement, current will take all possible paths but the strength ofcurrent in each path will be inversely proportional to theresistance of that path. However if one of the path has veryhigh resistance as compared to the other path (s), the current inthat path will be so samll that it can be safely neglected.
