Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

In a circuit with a 12V battery and three resistors in series (4Ω, 6Ω, and 2Ω), calculate the total current flowing through the circuit.

💡 Hint: Start by finding the total resistance, then use Ohm's Law.

Challenge 2 Hard

A circuit has two parallel resistors: 20Ω and 30Ω. If a voltage of 10V is applied, find the total current flowing into the circuit.

💡 Hint: Compute the total parallel resistance first.
