Question

In the circuit shown, the end A is at potential \( V_0 \), and end B is grounded. The electric current indicated in the circuit is

• A. \( \frac{V_0}{R} \)
• B. \( \frac{2V_0}{R} \)
• C. \( \frac{V_0}{3R} \)
• D. \( \frac{V_0}{2R} \)

Answer 1

The Correct Option is C

The current $i$ in the circuit is determined by the formula:
\[ i = \frac{V_0}{R_\text{eff}} \] where $R_\text{eff}$ is the effective resistance of the circuit. 
For the given configuration: \[ R_\text{eff} = R + 2R = 3R \]
