Grouping of Resistances
question_answer
The potential difference between points \[A\] and \[B\] of adjoining figure is [CPMT 1991]
A) \[\frac{2}{3}V\]
B) \[\frac{8}{9}V\]
C) \[\frac{4}{3}V\]
D) \[2\,V\]
Correct Answer:
C
Solution :
The given circuit can be redrawn as follows For identical resistances, potential difference distributes equally among all. Hence potential difference across each resistance is \[\frac{2}{3}V,\] and potential difference between A and B is \[\frac{4}{3}V.\]
