Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a circuit with a 24 V battery and three resistors in series: 4 Ω, 6 Ω, and x Ω. If the total current flowing is 2 A, what is the value of x?

💡 Hint: First calculate the total series resistance from the given current.

Challenge 2 Hard

In a parallel network with resistors of 3 Ω, 6 Ω, and x Ω connected to 30 V, find the value of x if the total current is 10 A.

💡 Hint: First determine the current through the known resistors.
