6 sample questions

Question 1.
What is the equivalent resistance of R1 = 4Ω and R2 = 6Ω connected in series?
Show hintHide hint
Add the resistances together.
Question 2.
If R1 = 4Ω and R2 = 6Ω are connected in parallel, what is the equivalent resistance?
Show hintHide hint
Use the formula: 1/Rtotal = 1/R1 + 1/R2.
3Question 3.
What does KCL state?
Show hintHide hint
Remember about how currents flow into and out of points.
4Question 4.
In a series circuit, how does the total resistance compare to individual resistances?
- Total resistance is less
- Total resistance is equal
- Total resistance is greater
Show hintHide hint
Consider how resistors add up.
Question 5.
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.
Show hintHide hint
Add series first, then handle parallel.
Question 6.
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.
Show hintHide hint
Handle parallel then sum with series!
