Short answer: Voltage is not a complete measure of potential energy any more than the height of a weight is a complete measure of potential energy. In order to calculate energy you must multiply the voltage by the amount of current (Amps) that can be supplied to get power. Then you multiply that power by the amount of time it can be supplied to get energy (power is energy per unit time). to get the potential energy of a weight suspended above the ground you must multiply the height of the weight by it's mass and multiply that by the gravitation acceleration (about 9.8 meters per second squared on earth).
Long answer: A 9V dry cell in a radio may only supply 111 milliamps for an hour or so while a 9V Golf cart battery can supply 111 amps for an hour. Therefore the radio battery has a potential energy of 3.6 Kilojoules while the golf cart battery has 1000 times that amount, 3.6 Megajoules.
Since a joule is equivalent to one kilogram accelerated over one meter at 1 meter per second squared and gravitational acceleration is 9.8 meters per second squared 3.6 Megajoules is about the same potential energy as a 1000 Kg (2200 pound) car at the top of a 367 meter (1200 feet) hill. The 9V battery has the potential energy of the same car .367 meters (1 foot 2.4 inches) up the hill. Quite a difference in potential energy.
What else can I help you with?
What are the potential applications of lithium dioxide in the field of energy storage and battery technology?
Lithium dioxide has the potential to be used in energy storage and battery technology due to its high energy density and stability. It could be used to create more efficient and longer-lasting batteries for electric vehicles, portable electronics, and renewable energy storage systems.
What type of energy is coal?
You could argue that it has stored potential energy.
What is protential energy?
The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. This stored energy of position is referred to as potential energy.
Can you use Aluminum sulfate and water in batterys?
Aluminum sulfate is not typically used in batteries. The electrolyte in batteries is usually made of chemicals like sulfuric acid or alkaline solutions. Using aluminum sulfate in batteries could be problematic due to its solubility and potential reactivity with other battery components.
Can alkaline batteries explode?
Yes, alkaline batteries have the potential to explode if they are subjected to extreme heat or are damaged. Overcharging, puncturing, or short-circuiting can lead to a buildup of pressure inside the battery, causing it to rupture or explode. It is important to handle and dispose of alkaline batteries properly to mitigate the risk of explosion.
Is it practical to connect batteries of different emfs in series?
You can connect batteries with different voltages in series (a 6 volt and a 12 volt would give you 18 volts), but never in parallel (difference of potential will create an arc, batteries could blow up).
Where could one type of energy be transferd into a different type of energy?
in an engine potential (gas) to thermal To kinetic
Why is potential energy called potential energy is it because the energy is not released but could be soon?
Because of its potential to do work.
What are the potential applications of lithium dioxide in the field of energy storage and battery technology?
Lithium dioxide has the potential to be used in energy storage and battery technology due to its high energy density and stability. It could be used to create more efficient and longer-lasting batteries for electric vehicles, portable electronics, and renewable energy storage systems.
If to vases are side-by-side on a shelf how could one have more potential energy?
IF the shelf is horizontal and both vases are absolutely identical, they will both have the same potential energy. However if they are different, then the vase that has the most mass will have more potential energy.
Does gravitational potential energy converted to electrical energy occur in routine operation of a car?
That could happen in an electric or hybrid car, when the car is coasting down a hill, converting gravitational potential energy to the car's kinetic energy, and a touch of the brakes puts some of that kinetic energy into the batteries. But it's a stretch.
What energy does your body energy convert?
Your body could could convert chemical energy into potential, kinetic, or mechanical energy.
How could you increase the potential energy in the apple?
You can increase the potential energy of an apple by raising it to a higher position, such as lifting it off the ground. The potential energy of an object increases with height because it has the potential to fall and convert that potential energy into kinetic energy as it descends.
How could you increase the energy of an object resting on a desk?
You could increase the energy of the object by applying a force to it in the direction of its movement or by raising it to a higher position above the desk. Both of these actions would increase the object's potential energy, which can be converted to kinetic energy when the object is released.
How could you use a flashlight to test two different brands of batteries to see which brand had more energy?
Well what you would do is you would put the first brand of batteries in the flashlight and you would time how long the batteries lasted and right it down . Then put the second brand of batteries in the flashlight and turn on the flashlight and time the flashlight and see how long the batteries lated and wright it down and you have your answer .
What does it mean when it says what forms of potential energy were displayed in the illustrations?
I assumed this question is on symbol interpretation. There are symbol on energy, for instance atom is for nuclear energy, lightning is for electricity, fire is for thermal energy, wood/plant is fuel derived from wood/plant, oil barrel for oil. From above example, wood/plant fuel is chemical potential and nuclear fuel is nuclear potential energy.
What is chemical energy transformed to?
It could be transfered to sound, thermal, and potential energy.
