Question: Using KCL, if three currents entering a node are 2A, 3A, and 1A, what is the current leaving the node?

Options:

  1. 6A
  2. 4A
  3. 3A
  4. 2A

Correct Answer: 4A

Solution: 

According to KCL, the sum of currents entering a node equals the sum of currents leaving. Therefore, Iout = 2A + 3A + 1A = 6A.

Questions & Step-by-Step Solutions

Using KCL, if three currents entering a node are 2A, 3A, and 1A, what is the current leaving the node?
  • Step 1: Identify the currents entering the node. In this case, they are 2A, 3A, and 1A.
  • Step 2: Add the currents entering the node together. Calculate 2A + 3A + 1A.
  • Step 3: The total of the currents entering the node is 6A.
  • Step 4: According to Kirchhoff's Current Law (KCL), the total current entering a node must equal the total current leaving the node.
  • Step 5: Therefore, the current leaving the node (Iout) is also 6A.
  • Kirchhoff's Current Law (KCL) – KCL states that the total current entering a junction must equal the total current leaving the junction.
