Question

potential difference across R1 and R2​

Answer 1

Answer:

Explanation:

In series combination the current simply passes through resistors and current do not divide so current is same in R1 and R2 . => Potential Difference is equal to the sum of potential drop across the individual resistors . From this we come to know that Current is same in R1 and R2 in series combination

Answer 2

Answer:potential Difference across R1 is 10v and that of R2 is 2v.

Explanation:It is accordingly that,

V= IR. Here, electric current is constant. Therefore, potential difference is direcly proportional to resistance.
