GATE 2016 EE (SET 1) Q15

15. Ra and Rb are the input resistances of circuits as shown below. The circuits extend infinitely in the direction shown. Which one of the following statements is TRUE?


If the equivalent resistance of first figure is R_{a}then from the second figure, we can see that $$R_{B}=R_{A}\parallel 1\Omega$$

$$R_{B}=R_{A}\setminus R_{A}+1$$
