(C) The resistance $R$ of a conductor is given by the formula:$R = \rho \frac{l}{A}$where $\rho$ is the resistivity,$l$ is the length,and $A$ is the cross-sectional area.Given that both conductors are made of the same material,their resistivities are equal: $\rho_{1} = \rho_{2} = \rho$.Given that they have the same length: $l_{1} = l_{2} = l$.Given that they have the same resistance: $R_{1} = R_{2} = R$.From the formula,we can express the area as $A = \frac{\rho l}{R}$.Since $\rho$,$l$,and $R$ are identical for both conductors,the cross-sectional areas must also be equal:$A_{1} = \frac{\rho l}{R}$ and $A_{2} = \frac{\rho l}{R}$Therefore,$\frac{A_{1}}{A_{2}} = 1$.

Two solid conductors are made of the same material,have the same length,and have the same resistance. One of them has a circular cross-section of area $A_{1}$ and the other has a square cross-section of area $A_{2}$. The ratio $\frac{A_{1}}{A_{2}}$ is
