Refer to the circuit diagram given in the figure. which of the following observations are correct?
A. Total resistance of circuit is \(6 \Omega\)
B. Current in Ammeter is 1 A
C. Potential across \(A B\) is 4 Volts.
D. Potential across CD is 4 Volts
E. Total resistance of the circuit is \(8 \Omega\).
Choose the correct answer from the options given below:

Pick an option to check your answer.
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.
