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
What is the potential difference measured in volts?
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
What does a battery create between terminals?
Potential difference (voltage)
It has a potential difference between the positive and negative terminals?
It is a battery.
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 should be pressures for 3 phase condenser?
Pressure is equal to voltage and is the potential deference between the capacitor two terminals
Because it has a potential difference between the positive and negative terminals what can act as an electron pump?
dry cell
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
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
Does a voltage have one terminal?
No. Voltage is the potential difference in energy between two charges. (Volts is joules per coulomb.) Since it is potential, that means it is relative, and in order to be relative, there must be two terminals.
What does coulombs law find?
The force between two charged particles.
What is the different between Coulomb and Faraday?
96485 Coulombs = 1 Faraday
Why do you have voltage on open circuit?
Voltage is simply electrical potential. You do not have to have current to have voltage, but you have to have both voltage and current in order to have power transfer.Voltage = joules per coulombCurrent = coulombs per secondWatts = Voltage times current = joules per secondAnswer'Voltage' is a synonym for 'potential difference', not potential. A potential difference exists between two points which are at different potentials due to an imbalance of their electrical charges.
How can two 4v lamps be lit up by two 2v cells?
-- Connect the cells in series. The two terminals of their series combination present a potential difference of 4 volts. -- Connect both lamps in parallel between the terminals of the series-connected cells.
