Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What is the total resistance of a 6Ω and 12Ω resistor in parallel?

💡 Hint: Use the formula \\( \\frac{1}{R_{total}} = \\frac{1}{6} + \\frac{1}{12} \\).

Question 2 Easy

If two resistors of 5Ω and 10Ω are in parallel, what voltage is the same across each if the source voltage is 20V?

💡 Hint: In parallel, voltage is the same.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A circuit contains three parallel resistors: 10Ω, 20Ω, and 30Ω. If a voltage of 60V is applied, calculate the total current supplied by the source.

💡 Hint: Calculate total resistance first using the parallel formula.

Challenge 2 Hard

Discuss how adding more resistors in parallel affects the overall current draw of a circuit and provide an example with calculations.

💡 Hint: Use the parallel formula to assess how current changes.
