Practice Questions

Test your understanding with targeted questions

Question 1 Easy

If a node has currents of 2 A entering and 2 A exiting, what can you conclude?

💡 Hint: Think about the currents entering vs leaving.

Question 2 Easy

What happens if the current leaving a node exceeds the current entering?

💡 Hint: Consider the conservation principle.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Three currents enter a junction: I1 = 5 A, I2 = 3 A, and I3 = x A leaves. What is the relationship to find x?

💡 Hint: Balance all currents using KCL.

Challenge 2 Hard

In a parallel circuit with two branches: 12 A enter, and Branch A has 7 A leaving. How much must Branch B leave to satisfy KCL?

💡 Hint: Consider charge conservation principles.
