How to Calculate Volts from Joules and Coulombs

Converting joules to volts is a fundamental calculation in electrical engineering and physics. It involves understanding the relationship between energy, charge, and potential difference. Our calculator simplifies this process, but it's important to understand the underlying principles.

Calculation Formula

The formula to calculate volts from joules and coulombs is:

\[V = \frac{J}{C}\]

Where:

  • V is the voltage in volts
  • J is the energy in joules
  • C is the charge in coulombs

Calculation Steps

  1. Identify the energy in joules (J)
  2. Identify the charge in coulombs (C)
  3. Divide the joules by the coulombs
  4. The result is the voltage in volts

Example Calculation

Let's calculate the voltage for 100 joules of energy and 20 coulombs of charge:

  1. Identify the given values: \[J = 100 \text{ joules}\] \[C = 20 \text{ coulombs}\]
  2. Apply the formula: \[V = \frac{J}{C} = \frac{100}{20} = 5 \text{ volts}\]

Therefore, 100 joules of energy across 20 coulombs of charge results in a potential difference of 5 volts.
