Answer 1

Answer:

Hope it helps

Please mark as brainliest

Explanation:

You need to know the overall potential difference across the resistor and the two resistor value which are in series. ... If the two resistor in series are r1 and r2 and potential difference across the two is V, then Vr1 = V * r1 / (r1+r2).

Answer 2

Answer:

the diffrence is 1 because r1-r2 =1
