What potential (voltage) exists between two power supply terminals if 5 joules of energy are required to move 10 coulombs of charge between the two terminals?
Half a volt, because the energy is the charge times the potential difference.
Another AnswerYou should be asking what the 'potential difference' is between the two terminals, not the 'potential'. Note that 'voltage' is another term for potential difference.

What is 1000 ohms?
"1,000 ohms" is the resistance of anything through which the current, expressed in amperes, is numerically equal to 0.001 times the potential difference between its terminals, expressed in volts.
What is the difference between EMF and terminal PD?
An electromotive force is the potential differenceappearing across the terminals of a battery, generator, etc., when that device is not supplying any load. When the device is supplying a load current, the electromotive force is equal to the sum of the voltage drops around the complete circuit, including any internal voltage drop.A potential difference (also known as a 'voltage'), as the name implies, is the difference in potential between two points.
What is the relation between energy and charge?
The relationship between energy and charge is potential difference or voltage. Where a volt is defined as existing between two points in an electric field when one joule of energy is required to move a charge of one coulomb between the two points.
How much potential difference is there between two identical charges?
There is no potential difference between identical charges
Can a solar panel generate volts but no amps?
A solar panel develops volts of EMF across its terminals when it's illuminated. If a conducting path is provided between its terminals, then amps of current flow. Just like any other battery or generator.
It has a potential difference between the positive and negative terminals?
It is a battery.
What does a battery create between terminals?
Potential difference (voltage)
How much is the potential difference between the terminals of a connection wire?
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.
Because it has a potential difference between the positive and negative terminals what can act as an electron pump?
A battery has a potential difference between its terminals due to a build-up of charge separation (positive and negative terminals). This potential difference can act as an electron pump by causing the flow of electrons from the negative terminal to the positive terminal through an external circuit, thereby generating electrical energy.
What is a voltage of a battery?
It is the potential difference between the positive and negative terminals of the battery. The unit of electrical potential is the volt, so the difference in potential between two ponts is also a quantity with units of volts, colloquially called the 'voltage' between the points.
What is the source that maintains a constant value of potential energy in its terminal?
A battery is a source that maintains a constant value of potential energy in its terminals. The chemical reactions within the battery create a potential difference between its terminals that remains constant as long as the battery is in good condition.
What electromotive force must be produced between the terminals of a DC source which requires 15Joules of energy to move a 6.0 C charges?
15 joules/6 coulombs = 2.5 joules per coulomb = 2.5 volts
What should be pressures for 3 phase condenser?
Pressure is equal to voltage and is the potential deference between the capacitor two terminals
How do you tell the difference between a cathode and anode?
A:The difference is potential a anode requires a positive potential and the cathode requires a negative potential ANSWER : I wander what a zener will behave with this explanation. Both have cathode and anode terminals
What type of energy is stored in energy?
Potential energy is stored in batteries. When a battery is charged, it gains potential energy due to the separation of charges between its terminals. This potential energy is then converted to electrical energy when the battery is connected to a circuit.
Why is it possible to measure an electric potential across the terminals of a dry cell?
Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?
Volts. Volts is another term for potential.
