Which of the following is true according to the junction rule, if total
current is 12 A?*

After the junction the current in path A is 6 and the current in path B is 2

After the junction the current in path A is 3 and the current in path B is 4

After the junction the current in path A is 8 and the current in path B is 4

After the junction the current in path A is 8 and the current in path B is 4

Explanation:

The junction rule states that the total current going into the junction equals the total current going out, so the total current in both paths must equal 12 if there are only two paths

6 + 2 = 8

3 + 4 = 7

8 + 4 = 12

the last one is the only one that adds up to 12
