3.2. Kirchhoff’s Current Law (KCL)

Try these first

1. 1.

   What does Kirchhoff's Current Law state?

   Hint

   Think about conservation of charge.

2. 2.

   Give an example of KCL in action.

   Hint

   Use simple numbers for clarity.

3. 3.

   What does KCL stand for?

   • Kirchhoff's Current Law
   • Kirchhoff's Circuit Law
   • Kirchhoff's Capacitance Law

   Hint

   No hint provided

4. 4.

   KCL applies to which type of currents?

   • True
   • False

   Hint

   KCL is universal in application.

5. 5.

   You have four currents at a node: I1 = -2A, I2 = 3A, I3 = -4A. What is I4?

   Hint

   Remember to account for the directions of the currents.

6. 6.

   In an AC circuit, if I1 = 2 sin(ωt), I2 = 5 sin(ωt + 30°), and I3 = 3A. Determine I4 using KCL.

   Hint

   Use phasor addition to solve.
