The formula to calculate the conversion from Joules to Coulombs (C) is:
\[ C = \frac{J}{V} \]
Where:
Let's say the energy in Joules (J) is 100, and the electric potential or voltage in Volts (V) is 10. Using the formula:
\[ C = \frac{100}{10} \]
We get:
\[ C = 10 \, \text{C} \]
So, the electric charge is 10 Coulombs.
