What happens to the total resistance in a circuit when two resistors are connected in series?.
- A.It decreases
- B.It increases
- C.It remains the same
- D.It becomes zero
Model answer
What a good answer should say
- It increases
Explanation
Why this works
When resistors are connected in series, the total resistance increases because the total resistance is the sum of the individual resistances. This is described by the formula R_total = R1 + R2 + ...
