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).

Which part of the circuit supplies the potential difference in the circuit?
The power source, typically a battery or a generator, supplies the potential difference in the circuit. This potential difference allows charges to flow through the circuit and power the electrical components.
How does a battery create potential energy?
A battery creates potential energy by storing chemical energy within it. This chemical energy is converted into electrical energy when the battery is connected in a circuit, generating a potential difference between the battery's terminals. This potential difference allows the flow of electrons through the circuit, thereby enabling the battery to power electronic devices.
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?
Please share your answer?
It has a potential difference between the positive and negative terminals?
It is a battery.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?
The difference in potential energy between the positive and negative terminals of a battery is expressed in volts.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
Why the unit of potential difference and electromotive force is the same?
Because an electromotive force is a potential difference (voltage) -specifically, an electromotive force is the open-circuit or no-load potential difference of a source such as a battery or generator.
Under what circumstances can the terminal potential difference of a battery exceed its emf?
"The potential difference between the terminals of a battery will equal the emf of the battery when there is no current in the battery. At this time, the current though, and hence the potential drop across the internal resistance is zero. This only happens when there is no load placed on the battery-that includes measuring the potential difference with a voltmeter! The terminal voltage will exceed the emf of the battery when current is driven backward through the battery, in at its positive terminal and out at its negative terminal." Raheel Ahmed Quaid i Azam University Islamabd Physics Dept
The potential difference supplied by the battery is 4.5 VCalculate the total energy transferred in 300s?
energy transferred = charge x potential difference.
