Question

a. current through R
b. value of R
c. potential difference across the battery​

Answer 1

Answer:

1. 2A
2. 5 ohm
3. 18 v

Explanation:

find R first. in series combination R is directly proportional to V.

R=(10/8)*4

the potential difference provided by the battery can be seen as PD across the resistances.

to find current apply I=V/R
