If I charge a van de graaff to say 10,000 V I would think of the voltage as electric pressure. There would be so many electrons looking to escape the metal ball, and this overcrowding of the electrons (electrostatic forces) would create electric pressure, or voltage. If my analogy is off, then the question I have might not make sense and I will have to revise. But I am wondering about an object that has a large deficit of electrons (positively charged). Does this object, just like the van de graaff, have a voltage associated with it? If so, would it be labeled any differently than a negatively charged object?
