Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Analyze a circuit with two junctions where currents I1 = 5 A enter, I2 = 2 A, and I3 = 3 A leave in junction A; at junction B, 4 A enter and I4 leaves. Find I4.

💡 Hint: Apply KCL at both junctions and set up equations.

Challenge 2 Hard

In a closed loop of a circuit with a 30 V supply and the voltage drops across three resistors of 10 V, 15 V, and unknown R, find R's voltage drop.

💡 Hint: Ensure to sum all voltage changes and set equal to the supply.
