Vedclass · Answer

(C) In the given ladder network, let the current flowing through the first series resistor $R$ be $I_1$. At each node, the current splits between the shunt resistor $2R$ and the next series resistor $R$. By analyzing the circuit from right to left, we observe that the current halves at each stage due to the symmetry of the ladder network. Specifically, if $I_1$ is the current entering the first series resistor, the current flowing through the subsequent shunt resistors will be $I_1/2, I_1/4, I_1/8$, and so on. The current $I$ in the final branch is given by $I = I_1/8$. Since the voltage across the first shunt resistor $2R$ is $V$, the current $I_1$ flowing through the first series resistor is $I_1 = V / (2R)$. Substituting this value into the expression for $I$, we get: $I = \frac{1}{8} 	imes \frac{V}{2R} = \frac{V}{16R}$.
