A) Six
B) Five
C) Four
D) Three
Correct Answer: C
Solution :
If all the resistance are to be used every time,\[N={{2}^{n-1}}\] If any number of the given n resistances can be used at a time, then\[N={{2}^{n}}-1\]where, \[N\] is the number of various possible values of equivalent resistances. In the given problem, it will be assumed that all are to be used every time. So, \[N={{2}^{3-1}}\]You need to login to perform this action.
