A)
4\[\Omega \] 8 V
B) 8 \[\Omega \] 4 V
C) 2 \[\Omega \] 2V
D) 16 \[\Omega \]8V
Correct Answer: A
Solution :
The equivalent resistance between A and B is \[\frac{1}{R}=\frac{1}{6}+\frac{1}{6}+\frac{1}{3}=\frac{2}{3}\] or \[R=\frac{3}{2}=1.5\,\Omega \] Now the equivalent resistance between A and B is \[R=1.5+2.5=4\,\Omega \] Now by Ohms law, potential difference between A and B is given by \[{{V}_{A}}-{{V}_{B}}=iR=2\times 4.0\] \[=8\,volt\]
