Answer & Solution

Correct Answer

(A) A, B and D Only

Step-by-step Solution

Detailed explanation


Current through ammeter \(=1 \mathrm{~A}\)
\(\mathrm{R}_{\mathrm{net}}=6 \Omega\)

\(\begin{aligned}
& \mathrm{V}_{\mathrm{AB}}=0.5 \times 4=2 \mathrm{volt} \\
& \mathrm{~V}_{\mathrm{CD}}=1 \times 4=4 \mathrm{volt}
\end{aligned}\)
A, B & D are correct.
