Question

Find the value of total resistance between X and Y in
ohm.-

1. R
2. 2R
3. 3R
4. R/2
2R
X
Y​

Answer 1

Answer:

1.r. as in first step we will calculate the resistance in series .

in second step r and r are in series

in third 2r and 2r in parallel

in fourth r and r in series

in fifth 2r and 2r in parallel

in sixth r and r in series and in seventh 2r and 2r in parallel

in last step it is r the resistance
