The relationship of voltage to charge is best described by the term capacitance. Capacitance is defined as the ability of a system to store an electrical charge. It is mathematically represented as the ratio of the electrical charge stored (in coulombs) to the voltage (in volts) across the system. Thus, capacitance indicates how much charge can be stored for a given voltage. This concept is fundamental in understanding how capacitors function in electrical circuits.

Current refers to the flow of electric charge, which is not directly about the relationship between voltage and charge itself. Conductance relates to how easily electricity flows through a material, while impedance involves the total opposition to the flow of alternating current, which includes both resistance and reactance. While these concepts are interconnected in the realm of electrical engineering, capacitance specifically correlates voltage directly with charge, making it the correct choice.
