The primary reason one would use 220 volts would be to reduce the current by 1/2. This allows smaller wire and breaker. However, you are charged by the kilowatt hour which will likely be about the same for the two voltages. The only advantage might be that the 220 volt unit might cost less and possibly have a higher efficiency. You just need to compare the kilowatt hr ratings for the two units. The voltage is essentially irrelevant without additional information.

Will you save buying a 220 volt ac than a 110?
Yes, in the long run. The 220 volt unit will use less power.
What is the unit of potential difference?
The unit for electric potential difference is the volt (V).
What unit shows the difference in charge between two points?
I don't think such a unit is used, or would make much sense, in physics. That sounds like the description of voltage - unit volt. However, the volt is not really a difference in electric charge, but rather, of electric potential. It can be understood as potential energy related to electric fields: if there is an electric potential between two points, it requires a certain amount of energy to move a unit charge from one point to the other. Thus, the unit volt is equivalent to joules / coulomb.
What unit would be used to measure the potential difference between two poles of a battery?
The volt.The volt.The volt.The volt.
What is the unit of electrical voltage?
The Volt
What is a unit of measure that expresses potential difference between two electrodes in a battery?
Volt
What is the unit of measure for electtric potential?
The 'volt' is. 1 volt = 1 joule per coulomb
Who was volt?
Not "Volt" - but "Volta". The unit "volt" was named Alessandro Volta.
The unit to measure current is the volt?
The unit of current is the ampere. The unit of potential difference, or electromagnetic force is the volt.
How is volt related to ohm and ampere?
1 ohm is the resistance of anything that measures 1 volt between its ends when 1 ampere of current flows through it.
