In the circuit shown in figure, current through \[{{R}_{2}}\] is zero if \[{{R}_{4}}=2\Omega \] and \[{{R}_{3}}=2\Omega \]. In this case:

A) Current through \[{{R}_{3}}=2.5A\]                           

B) Current through \[{{R}_{4}}=3A\]

C) Both and are correct                          

D) Both and are wrong

Correct Answer: D

Solution :

[d] Current through \[{{R}_{3}}=\frac{20V}{4\Omega }=5A\] Current through \[{{R}_{4}}=\frac{5V}{2\Omega }=2.5A\]
