Question

In following circuit, terminal $A,B,C$ and $D$ are maintained at same potential. An ideal battery of emf $E$ is connected across the points $x$ and $y.$ The resistance of each resistor is $R.$

Determine the current through the battery.

• A. $\frac{E}{R}$
• B. $\frac{2E}{R}$
• C. $\frac{E}{8R}$
• D. $\frac{E}{2R}$

Answer 1

The correct option is B $\frac{2E}{R}$
