Explanation: Conductance is the correct term for the ratio of current through a conductor to the voltage producing it. This relationship stems directly from Ohm's Law, which states $V = IR$ (Voltage equals Current times Resistance). If we rearrange Ohm's Law to solve for the ratio of current to voltage ($I/V$), we get $I/V = 1/R$. The reciprocal of resistance ($R$) is defined as conductance ($G$), meaning $G = 1/R$. Therefore, conductance is precisely the ratio of current to voltage ($I/V$), and it is measured in Siemens. Conversely, resistance (C) is the inverse ratio, defined as voltage divided by current ($V/I$), representing the opposition to current flow. Inductance (A) is a different electrical property of a component, typically a coil, representing its opposition to changes in current, measured in Henrys, not a direct ratio of steady-state current to voltage.
