Question

find a total resistance with the total current drawn from the battery see potential difference from B and C​

Answer 1

Explanation:

Given : R1 = 5 ohm

R2 = 10 ohm

RA = 10ohm , R2 = 5 ohm

R1 and RA are in series hence thier sum will be..

5 ohm + 10 ohm = 15 ohm

similary, R2 and R2 are in series

hence , their sum will be

10 ohm + 5 ohm = 15 ohm

now, R1 and RA are parallel to R2 and R2

so, their sum will be

1/15 ohm + 1/15 ohm = 2/15 ohm

i.e. Req = 15/ 2 = 7.5 ohm ......

hope, it helps u ....
