Twelve wires of equal resistance R are connected to form a cube. The effective resistance between two diagonal ends A and E will be:

1. $\frac{5\mathrm{R}}{6}$

2. $\frac{6\mathrm{R}}{5}$

3. $12\mathrm{R}$

4. $3\mathrm{R}$

The potential difference \(V_\mathrm{A}-V_\mathrm{B}\) between the points \(\mathrm{A}\) and \(\mathrm{B}\) in the given figure is:
    

The current through the 5 $\mathrm{\Omega }$ resistor is:

1. 3.2 A                     

2. 2.8 A

3. 0.8 A
