Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the total resistance of a 6Ξ© and 12Ξ© resistor in parallel?
π‘ Hint: Use the formula \\( \\frac{1}{R_{total}} = \\frac{1}{6} + \\frac{1}{12} \\).
Question 2
Easy
If two resistors of 5Ξ© and 10Ξ© are in parallel, what voltage is the same across each if the source voltage is 20V?
π‘ Hint: In parallel, voltage is the same.

Question 1
A circuit contains three parallel resistors: 10Ξ©, 20Ξ©, and 30Ξ©. If a voltage of 60V is applied, calculate the total current supplied by the source.
π‘ Hint: Calculate total resistance first using the parallel formula.
Question 2
Discuss how adding more resistors in parallel affects the overall current draw of a circuit and provide an example with calculations.
π‘ Hint: Use the parallel formula to assess how current changes.
