The relationship between volts and joules involves the concept of energy, and it depends on the amount of charge (measured in coulombs). The formula connecting voltage (V), energy (Joules), and charge (Coulombs) is:
\[
\text{Energy (J)} = \text{Voltage (V)} \times \text{Charge (C)}
\]
So, to calculate how many volts 1 joule is, you also need to know the charge (in coulombs).
If you have 1 coulomb of charge, the equation would be:
\[
1 \text{ Joule} = \text{Voltage (V)} \times 1 \text{ Coulomb}
\]
This means that with 1 coulomb of charge, 1 joule of energy would correspond to 1 volt.
However, without knowing the amount of charge, you can't directly convert joules to volts. The relationship depends on how much charge is involved!
