Answer 1

Answer:

pic is not clear plz repeat it.

Answer 2

Hey mate for this question you need to know the symmetric Circuits

Refer the attachment for Diagram and few details

Form the diagram(Attchment waali) It is clear that each wire has 2 resistances are in series

Hence for each wire Equivalent resistance is given by

$R=_{s}=R_{1}+R_{2}=1+1=2ohm$

Each wire has a resistance of 2 ohm and are in parallel

hence Resultant (Total) Resistance is given by

$\frac{1}{R_{p}}=\frac{1}{R_{1}}\frac{1}{R_{2}}+\frac{1}{R_{3}}$

$\frac{1}{R_{p}}=\frac{1}{1}+\frac{1}{1}\frac{1}{1}=3$

$\frac{1}{R_{p}}=3$

$R_{p}=\frac{1}{3}$

The resultant resistance is

$\red{R_{equivalent}=\frac{1}{3}\:or\:0.33}$
