The constant of proportionality between charge and voltage is the:. a) Capacitor
b) Capacitance
c) Farad
d) None of the above

The constant of proportionality between charge and voltage is the capacitance.

Explanation:

The capacitance (), measured in farads, is the ratio of charge to voltage, that is:

Where:

- Charge, measured in coulombs.

- Voltage, measured in volts.

If charge is clear, it is easy to concluded that capacitante is a constant of direct proportionality.

Hence, the correct answer is B.
