Question

three 1 ohm resistors are connected to form a triangle,the resistance between any two corner is ​

Answer 1

Answer:2/3

Explanation:

As you know that there are three resistances.Any Two resistances are connected in series in triangle.So,

R=R1+R2=1+1=2

And after this , we have two resistances.One is 1 ohm and second is 2ohm.They are connected in parallel.So,

1/Re=1/R3+1/R=1/1+1/2=3/2

Take reciprocal

*Re=2/3*

Answer 2

Answer:

the above one is the correct answer
