Practice Questions
Test your understanding with targeted questions
What is the equivalent resistance of R1 = 4Ω and R2 = 6Ω connected in series?
💡 Hint: Add the resistances together.
If R1 = 4Ω and R2 = 6Ω are connected in parallel, what is the equivalent resistance?
💡 Hint: Use the formula: 1/Rtotal = 1/R1 + 1/R2.

If R1 = 5Ω, R2 = 10Ω and R3 = 1Ω are connected in series and R4 = 2Ω is in parallel with the combination. Find the total equivalent resistance.
💡 Hint: Add series first, then handle parallel.
In a complex circuit where R1 = 15Ω and R2 = 25Ω are parallel, and this pair is in series with R3 = 10Ω, find the total resistance.
💡 Hint: Handle parallel then sum with series!
