Find the voltage \(V_2\) across \(R_2\) for the given circuit
- A \(0.56 \mathrm{~V}\)
- B \(1.61 \mathrm{~V}\)
- C \(0.63 \mathrm{~V}\)
- D Can not be determined.
Answer & Solution
Correct Answer
(D) Can not be determined.
Step-by-step Solution
Detailed explanation
Using Kirchhoff's loop rule, we get \( \begin{aligned} 12 V & =8 i_1+2\left(i_1-i_2\right) \\ 6 V & =2\left(i_2-i_1\right)+i_2 R_3+2 i_2 \end{aligned} \) As value of \(R_3\) is not given solution cannot be found (data insufficient).
