1A
3A
5A
9A
According to Kirchhoff's Current Law, the total current entering a junction equals the total current leaving it. Total entering = 2A + 3A + 4A = 9A.

Q: According to Kirchhoff's Current Law, if three currents enter a junction as 2A, 3A, and 4A, what is the total current leaving the junction?
Solution: According to Kirchhoff's Current Law, the total current entering a junction equals the total current leaving it. Total entering = 2A + 3A + 4A = 9A.
Steps: 5
Step 1: Identify the currents entering the junction. In this case, they are 2A, 3A, and 4A.
Step 2: Add the currents that are entering the junction together. Calculate 2A + 3A + 4A.
Step 3: Perform the addition: 2A + 3A = 5A, then 5A + 4A = 9A.
Step 4: According to Kirchhoff's Current Law, the total current entering the junction (9A) must equal the total current leaving the junction.
Step 5: Therefore, the total current leaving the junction is 9A.
