Question

three resistance R1 R2 and R3 are connected in series so that the equivalent resistance Rs is equals to Rs=R1 +R2+R3​

Answer 1

Answer:

hope this is the answer you are looking for

Explanation:

Here R2 and R3 are in parallel so the voltage across them is same. Suppose the voltage across R1 is V1 and voltage across R2 is V2.

And also the current flowing in R1 and in the parallel combination other two is same.Let it be I

then V1=I × R1

V2=I(R2×R3/R2+R3)

Now V1/V2=R1(R2+R3) / R2×R3
