Joules to Volts Calculator
Volts and Joules are both International System units, which are strongly related when it comes to electric power and energy.
Although sometimes people talk about electricity using both of them, they represent concepts with few little but notable differences.
That’s why I will talk about the definition of each measurement unit and how to convert Joules into Volts.
What do Joules (J) represent?
We use Joules to represent energy or heat. In physics, they show up in questions like “How much energy will be necessary to…?” So, in topics related to electricity, we use joules to describe how much electric power should be used to perform specific tasks.
For example, if you used a crane, you would like to know the weight of the object to carry to know how much energy will be necessary to complete the task successfully.
Additionally, there is a physical phenomenon called the “Joule effect,” which says that every electric conductor will produce heat when energy is flowing through it.
What do Volts (V) represent?
Volts are the measurement unit of one of the three components of the famous “Ohm Law”: Voltage; the other two elements are Electric current (Amperes) and Resistance (Ohms).
If we want to understand electricity easily, we can think of it as a river coming down a mountain.
Voltage would be how much inclined the mountain is; so, the more inclined the mountain is, the faster the water will be (electric current). With this in mind, we define Voltage as the amount of electricity able to be produced between to points.
Now that you know the definitions of each unit, we can briefly say that you use Volts to predict how much electricity you can produce, and you use Joules to know how much of that electricity you need to use. Now, let’s see the formula.
Formula to convert Joules into Volts
Before seeing the equation, I have to introduce you to a new measurement unit necessary in this calculation: the Coulomb (C); it is a unit used to know the amount of energy that the electric charges produce on the whole.
Now, you are ready to use this formula:
Volts = Joules / Coulombs
Note: Don’t forget that Coulombs are usually represented in scientific notation, which means that they are multiplied by a power of 10.
If you don’t consider that, your result could be either higher or lower than expected.
