Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a parallel circuit with three resistors of 4Ω, 8Ω, and 2Ω. Calculate the total current if connected to a 24V source.

💡 Hint: Calculate resistance first to find the total current.

Challenge 2 Hard

In a parallel circuit with two branches having resistances of 10Ω and 5Ω. If the voltage supplied is 15V, what current flows through each branch?

💡 Hint: Remember to calculate individually for each resistor using Ohm's Law.
