Vedclass · Answer

(D) The circuit is a bridge circuit. Let the nodes be $A$ and $B$. The equivalent resistance $R_{AB}$ depends on the values of $R_1, R_2,$ and $R_3$. Specifically,for this symmetric bridge configuration,the equivalent resistance $R_{AB}$ is given by the parallel combination of the upper and lower branches. Since the circuit is symmetric,the equivalent resistance $R_{AB}$ is a function of all three resistors $R_1, R_2,$ and $R_3$. Therefore,the correct statement is that the equivalent resistance depends on $R_1, R_2,$ and $R_3$.

The equivalent resistance between ends $A$ and $B$ is
