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)+I4 (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

according kirchoff\'s loop rule

      I3 (6 ohm ) + I4 (12 ohm ) = 0

Answer is A

when I3 and I4 are moving in same direction, if the current directions are reversed, B is the answer.
