Questions & Step-by-Step Solutions

According to Kirchhoff's Current Law, if three currents entering a junction are 2A, 3A, and 5A, what is the total current leaving the junction?
Correct Answer: 10A
  • Step 1: Identify the currents entering the junction. In this case, they are 2A, 3A, and 5A.
  • Step 2: Add the currents that are entering the junction together. So, calculate 2A + 3A + 5A.
  • Step 3: Perform the addition: 2A + 3A = 5A, then 5A + 5A = 10A.
  • Step 4: According to Kirchhoff's Current Law, the total current entering the junction (10A) must equal the total current leaving the junction.
  • Step 5: Therefore, the total current leaving the junction is 10A.
  • Kirchhoff's Current Law – The principle that the total current entering a junction must equal the total current leaving the junction.
