Questions & Step-by-Step Solutions

What is the total current flowing through a junction where 5A enters and 3A and 2A leave?
Correct Answer: 5A
  • Step 1: Identify the current entering the junction. In this case, it is 5A.
  • Step 2: Identify the currents leaving the junction. Here, they are 3A and 2A.
  • Step 3: Add the currents leaving the junction together. 3A + 2A = 5A.
  • Step 4: According to Kirchhoff's Current Law, the total current entering (5A) should equal the total current leaving (5A).
  • Step 5: Since both sides are equal, the total current flowing through the junction is confirmed to be 5A.
