In the diagram above , the current I is

  • 3/8
  • 9/11 checkmark
  • 11/9
  • 8/3

The correct answer is: B

Explanation

I = _E
R+r

For parallel of 5ÎĐ and 10ÎĐ
1/R = 1/10 + 1/5 = 1+2/10 = 3/10
âˆīR = 10/3
Total R = 31/3 + 3 x 1 = 71/2
âˆīI = 6/71/3 = 6/1 x 3/22 = 18/22 = 9/11
âˆīI = 9/11

There is an explanation video available .
