Four identical resistances are joined as shown in the figure. The equivalent resistance between points A and B is `R_(1)` and that between A anc C is `R_(2)` then ratio `R_(1)//R_(2)` is

Options

A. `1:1`
B. `4:3`
C. `3:4`
D. `1:2`

Answer

C

Explanation

`(R_(AB))/(R_(AC))=(R_(1))/(R_(2))=((3xx1)/(3+1))/((2xx)/(2+2))=3/4`
