What is the current \(I\) shown in the given circuit?

- A \(\frac{V}{2 R}\)
- B \(\frac{V}{R}\)
- C \(\frac{V}{16 R}\)
- D \(\frac{V}{8 R}\)
Answer & Solution
Correct Answer
(C) \(\frac{V}{16 R}\)
Step-by-step Solution
Detailed explanation
According to the question, Total resistance of the given circuit \[ R_{\mathrm{eq}}=2 R \] \(\therefore \quad I=\frac{V / 2 R}{8} \quad\left(\because I_{1}=V / 2 R\right)\) So, current \(I\) in the circuit \(I=\frac{V}{16 R} \quad\left(\because I=\frac{I_{1}}{8}\right)\)
