Voltage has the dimensions of energy / charge, in SI units, J/C. Depending on what you mean by "energy ... available", you can simply divide the energy by the charge. If there is a certain number of volts between two points - for example 10 volts - that means that every coulomb of charge gains 10 joules of energy in one direction, or loses 10 joules of energy in the other direction.

How many joules of energy does each coulomb of charge have at the battery terminals?
That depends on the voltage. In general, a coulomb of charge will either gain or lose (depending on the direction) one joule of energy for every volt of potential difference. For example, if the battery has 12 V, a coulomb of charge will gain or lose 12 joules of energy when going from one terminal to the other.
Does a transformer boost electric energy?
The transformer doesn't "boost" energy. If the voltage on the output side is higher than the voltage on the input side, then the current is lower. The power (energy every second) on either side is the product of (voltage) times (current), and that product is the same on both sides of the transformer.
What holds an electrical charge?
Just about every matter has charge, it is the movement of charge that is described by electricity.
When an electrical charge moves from a higher potential energy to a lower potential energy does what?
when an electric charger moves from higher to lower potential energy, it supplies energy to us but when it is moved from lower to higher potential, we have to supply energy to it........... because every thing has a tendency to move from a point of higher potential to lower potential........
What is energy produced by?
magnetic energy is produced by every current carrying conductor. every moving charge produces magnetic field which can be converted to magnetic energy as per needed.

What type of energy do you have when you run?
you have renewable energy because when you sleep, your energy charges. If it didn't charge, you won't be able to move every day.
Does the brigthness of a bulb stay the same in a parellel circuit no matter how many bulbs are there?
If all the bulbs are connected in parallel, and there is enough current, yes, the brightness will be the same. The voltage (which is the amount of energy in every charge), remains the same for all bulbs
Why does capacitor supply reactive power?
A capacitor needs current to flow into and out of it before a voltage is developed across it, so in an ac circuit the current in a capacitor is 90 degrees or a quarter-cycle in front of the voltage. In a 50 Hz system the cycle period is 20 milliseconds so the current peak is 5 milliseconds before the voltage peak every time. The energy in the capacitor is the charge times the voltage, and energy flows into the capacitor and back into the supply twice per cycle. No net energy is dissipated in the capacitor. All the energy is reactive, in other words it flows in and out. The power-factor of the capacitor seen as a load is zero.
Can you get 2 energy packs in Mafia Wars in one day?
No. Energy packs are available every 24 hours
What happens at every ascending level of the pyramid of energy?
energy is increased, unless the real answer is...the amount of available energy is decreased..or it could be BIG FACE 100s
What are the differences between 'voltage' 'current' 'frequency' 'conductance' and 'power' in regards to electricity?
They describe completely different things.* Voltage: The energy required to move a unit charge between two points * Current: Roughly speaking, the amount of electrons that pass every second * Frequency: The number of cycles per second (for an alternating current) * Conductance: How easily a material will conduct electricity * Power: The amount of energy converted per second
Does automatic voltage regulators consume energy?
Yes. Almost every electronic device consumes energy, however small. However the power draw of a voltage regulator is extremely tiny, typically less than 1mA. As such, they usually save more power than they consume.
How does the increasing the voltage in a circuit affect the energy of the electrons flowing in the circuit?
"How does increasing the voltage in a circuit affect the energy of the electrons flowing in the current?" Answer: The charge of an electron is constant. Every electron has a charge of something like 1.6 x 10^-19 coulombs. (The mass of an electron is also constant which will be important below). When the current in a simple direct-current electrical circuit is 1.0 Ampere there are 6.25 X 10^+18 electrons/second (or 1.0 coulomb of charge) flowing past a given point in the circuit (this is by definition or convention). The voltage (V) is equal to the current (I) times the resistance (R), or V=IR. So, in a simple direct current circuit where the resistance is constant (we will just assume that for the sake of simplicity), if we increase the voltage, the current must increase proportionately. This means the total charge passing a given point in the circuit must increase. This means that more electrons must pass a given point in the curcuit every second. Since the charge of every individual electron is constant there must be more electrons moving past a given point every second.What actually happens to the energy of the electrons flowing in the circuit depends on the geometry of the circuit. If the electrons are forced to travel in single-file (like cars on a one lane road), then in order for more of them to pass a given point every second, their velocity must increase. In this case, their energy would also increase according to the formula for kinetic energy (KE) of a moving particle KE=1/2MV^+2 (or one half the mass (M) times the velocity (V) squared). (This is where we have to remember that electrons are particles with constant mass too.) In this case, the energy increases with the square of the velocity of the moving electrons. However, if the electrons still travel at the same speed but on different paths (like cars on a multi-lane highway) so that more of them can get past a given point every second, then their energy doesn't change. In reality the resistance (R) also generally increases with an increase in voltage (V) so the current (I) may not increase in direct proportion to the voltage but the current will generally increase until too much heat and resistance occurs. The heat generated by such a circuit is proportional to the square of the current which is pretty dramatic.
