Consider the loop including the 6 and 12 Ohm resistors Which
     Consider the loop including the 6 and 12 Ohm resistors. Which of the following is correct?  13 (6.00 Ohm)+14 (12.00 Ohm)=0  13 (6.00 Ohm) minus 14 (12.00 Ohm)=0  12 +13 (6.00 Ohm)+14 (12.00 Ohm)=0  none of the above   
  
  Solution
(B) as we can see that potential across 6 ohm and 12 ohm resistors are equal.
I3(6)=I4(12)
I3(6)-I4(12)=0
