Questions & Step-by-Step Solutions
Using Kirchhoff's Current Law, if three currents enter a junction as 2A, 3A, and I, what is the value of I if the total current leaving the junction is 5A?
Step 1: Identify the currents entering the junction. We have three currents: 2A, 3A, and I.
Step 2: Calculate the total current entering the junction. Add the known currents: 2A + 3A = 5A.
Step 3: Identify the total current leaving the junction. It is given as 5A.
Step 4: Apply Kirchhoff's Current Law (KCL), which states that the total current entering a junction equals the total current leaving the junction.
Step 5: Set up the equation: total entering = total leaving. This means 5A (from Step 2) + I = 5A (from Step 3).
