Physics - Current Electricity Question with Solution | TestHub

$R_4$ and $R_5$ are equal resistors in parallel, so they share current equally - (A) is correct.

The $R_3$ branch has resistance $R_3+(R_4\parallel R_5)=2+1=3\Omega$, equal to $R_2=3\Omega$; both sit between the same two nodes, so $I_{R_2}=I_{R_3}$ - (B) is correct.

$I_{R_1}=I_{R_2}+I_{R_3}$ and $I_{R_3}=I_{R_4}+I_{R_5}$. Since $I_{R_2}=I_{R_3}$, substituting gives $I_{R_1}=I_{R_3}+I_{R_4}+I_{R_5}$ - (C) is correct.

Similarly $I_{R_1}=I_{R_2}+I_{R_3}=I_{R_2}+I_{R_4}+I_{R_5}$ - (D) is also correct.
