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:
- A A, B and D Only
- B A, B and C Only
- C A, C and D Only
- D B, C and E Only
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.
