The maximum amount of charge you can store on the sphere is what we mean by its capacitance. The voltage (V), charge (Q), and capacitance are related by a very simple equation: C = Q/V. So the more charge you can store at a given voltage, without causing the air to break down and spark, the higher the capacitance.
