Challenge Problems

Push your limits with challenges.

Question 1

A circuit contains a resistor of 10Ξ© and a voltage of 60V. Calculate the current flowing through the circuit. Then if the resistance doubles, what is the new current?

πŸ’‘ Hint: Apply Ohm's Law for both scenarios.

Question 2

Design an electrical circuit with a voltage source of 9V, a 3Ξ© resistor, and a 6Ξ© resistor connected in parallel. Determine the total current from the voltage source.

πŸ’‘ Hint: Start by calculating the equivalent parallel resistance first.
