Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a circuit diagram with two branches, applying KCL and KVL to find unknown currents and voltages.

💡 Hint: Make your equations based on the flows of current and the voltage drops in your diagram.

Challenge 2 Hard

Given a circuit with a 12V source, a 3A current flowing into a node, and two paths leading out: one path with 2A and another unknown. Calculate the unknown current using KCL.

💡 Hint: Remember to set up your equation based on flows at the junction.
