Why can't two capacitor plates be far away from each other if it's really just the battery creating the potential difference between the plates?

Capacitance is directly proportional to the area of the plates divided by the distance between the two plates. The farther away the plates are the lower capacitance will be.
A capacitor stores energy in the electric field between the two plates. If those plates are very far apart, the field gets crappy real fast.

When a battery is connected with a capacitor the potential difference will?
Charge the capacitor. Potential difference is a scientific term for what is more commonly called voltage. ANSWER: If big enough the battery will see a short initially and then proceed to charge the capacitor at a rate of 63% of the voltage in one time constant defined as RC For engineering purposes after 5 time the time constant the battery will and the capacitor zero potential different. The proper term should be virtual no difference.
What is used to store potential electrical energy?
A Battery or a capacitor.
What happens to charge and potential difference and capacitance in the presence of dielectric when the battery is disconnected from the capacitors?
The capacitor will hold the charge, until it leaks off due to resistances in the dielectric or external.
What generates electrical energy from chemical energy?
A battery stores chemical energy creating a voltage or potential difference that is the potential to do work.When a battery is connected to an electrical device, current flow and is so the conversion of chemical energy into electrical energy.
Explain how potential difference in a battery is similar to a staircase?
The potential difference in a battery is like the height of the stairs. The amount of charge separated in a battery is like the mass moved up the stairs. The potential energy in the battery is due to both the potential difference (volts) and the amount of charge that has been separated (coulombs).
If a 0.40-uF capacitor is connected to a 9.0-V battery how much charge is on each plate of the capacitor?
The units of capacitance are called farads. A one farad capacitor is a capacitor with 1 volt potential difference with 1 coulomb of charge on the capacitor, C = Q/V or Q=CV So the charge held on your capacitor is Q = CV = 9Volts * 0.40*10-6Farads=3.6*10-6 Coulombs
Why does each plate receive charge of exactly same magnitude?
the plates of capacitor are connected to the same battery so same potential difference will develop across the plates of capacitors, as a result charges of same magnitude will be stored, as the charges are being supplied by the same battery.
What will happen if you connect 12volt battery to a 240VOLT capacitor?
If the capacitor is charged then the battery will explode.
Why does a battery work?
A battery s a source of constant potential difference , this potential difference drives the electrons present in the wire and this constitutes current .Shortly the potential difference across the battery terminals does work on the conduction electrons present inside the conductor. Actually a battery is an electrolytic device ,after some time the electrolyte completely exhausts this state of battery is called as discharged state.
What is terminal PD?
A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
What does a battery create between terminals?
Potential difference (voltage)
What is the potential difference across the terminals of a battery?
