Expert Answer:

The equivalent resistance will be as follows
 
 
 
begin mathsize 12px style Two space straight R space are space parallel space hence space its space equivalent space resistance space will space be fraction numerator 1 over denominator straight R apostrophe end fraction space equals space 1 over straight R space plus space 1 over straight R space straight R apostrophe space equals space straight R over 2 straight R apostrophe space is space then space series space with space straight R space hence space equivalent space circuit space will space be straight R
