Question 1.
What is the total resistance of two resistors in series with values of 4Ω and 6Ω?
Show hintHide hint
Add the two resistances together.
Question 2.
How would total resistance be affected if another resistor of 2Ω is added in series to 3Ω?
Show hintHide hint
Remember to add it to the existing resistance.
3Question 3.
What is the total resistance of three resistors of 2Ω, 3Ω, and 5Ω in series?
- 5Ω
- 10Ω
- 3Ω
Show hintHide hint
Remember to sum the resistances.
4Question 4.
In a parallel circuit, what stays the same across all components?
- Voltage
- Current
Show hintHide hint
Think about how voltage behaves in parallel.
Question 5.
You have resistors of 10Ω, 5Ω in series; how to calculate the resistance if another 2Ω resistor in parallel is added?
Show hintHide hint
Use both series and parallel formulas.
Question 6.
A circuit has 4Ω and 6Ω resistors in series with a parallel of 2Ω. What is the total resistance?
Show hintHide hint
Remember the order of operations.
