I have doubts in these questions .
1 . Three resistors each of 2 ohms are connected together , so that their resistance is 3 ohms . draw a diagram to show this arrangment and check it by calculation .
2 . when two resistors of resistance R1 and R2 are connected in parallel , the net resistance is 3 ohms . when connected in series its value is 10 ohms . calculate the values of R1 and R2 .

Expert Answer:

### 1. R_{1} = R_{2} = R_{3} = 2 Ω
The resultant resistance is 3 Ω. Hence, the combination will be 2 resistors in parallel and their combination in series with the third.
The resistance between A and B is
This is in series with R_{3}. So, we get
R = R_{s} + R_{3} = 1 + 2 = 3 Ω
**NOTE: Kindly post the other question as a separate query.**

_{1}= R

_{2}= R

_{3}= 2 Ω

_{3}. So, we get

_{s}+ R

_{3}= 1 + 2 = 3 Ω

**NOTE: Kindly post the other question as a separate query.**
