Current arises from the "flow" of charge. Resistors let you choose how much current flows for a given voltage since you can think of wires as having no resistance (simplified). In short: Resistors limit the flow of electrons, reducing current. Voltage comes about by the potential energy difference across the resistor.

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.
