Questions & Step-by-Step Solutions

Using KCL, if three currents enter a node: 5A, 3A, and 2A, what is the current leaving the node?
  • Step 1: Identify the currents entering the node. In this case, the currents are 5A, 3A, and 2A.
  • Step 2: According to Kirchhoff's Current Law (KCL), the total current entering a node must equal the total current leaving the node.
  • Step 3: Add the currents entering the node: 5A + 3A + 2A.
  • Step 4: Calculate the sum: 5A + 3A = 8A, then 8A + 2A = 10A.
  • Step 5: Set the total current entering equal to the current leaving the node: Iin = Iout.
  • Step 6: Since the total current entering is 10A, we have Iout = 10A.
