Question

Determine the value of R2 in terms of R0 and N in the circuit shown below is?

(a) R2 = NR0/(N^2-1)

(b) R2 = 2 NR0/(N^2-1)

(c) R2 = 3 NR0/(N^2-1)

(d) R2 = 4 NR0/(N^2-1)

This question was posed to me in homework.

Answer 1

Right answer is (b) R2 = 2 NR0/(N^2-1)

Easy explanation: NR2 = R1+R0+R2. On substituting the value of R1, we get the value of R2 in terms of R0 and N as R2 = 2 NR0/(N^2-1).
