Question

A network of six identical resistors , each of
value R is made
as shown in the figure .
Equivalent resistance
between hout A and B is:

a) R/4 (6) 3R/4 (c) 4R/3 (d) 3R​

Answer 1

Answer:

avoid the common wire and connect the points A & B

then,

R/2 +R is parallel to R/2 +R

so 3R/2 is parallel to 3R/2

so Req= 3R/4

Answer 2

Refer to the attached image ☺️

Formula used :-

Req = R1 + R2 (series)

1/Req = 1/R1 + 1/R2 ( parallel)
