In the circuit shown below, find the value of I1/I2.

(a) (R1-R2+R0)/R2

(b) (R1+R2+R0)/R2

(c) (R1-R2-R0)/R2

(d) (R1+R2-R0)/R2

I had been asked this question in class test.

This intriguing question originated from Attenuators topic in portion Filters and Attenuators of Network Theory

Right answer is (b) (R1+R2+R0)/R2

To explain I would say: R2(I1-I2)=I2(R1+R0)

=>  I2(R2+R1+R0)I1R2. On solving, I1/I2=(R1+R2+R1)/R2.
