Convert volts to joules instantly using this free calculator. Understand the energy stored or used in electrical systems. Works for capacitors and basic physics problems.
Quick Intro: Convert Volts to Joules
To convert volts to joules, you use the formula for energy stored in a capacitor: Joules = 0.5 × Capacitance × Voltage². This equation calculates the electrical energy based on the voltage applied and the capacitance value of the component.
Volts to Joules Calculator Overview
This Volts to Joules Calculator helps you convert voltage into energy (joules) in electrical circuits, especially useful for capacitors and physics problems. In basic terms, a joule is the amount of energy transferred when one ampere of current flows through a resistance of one ohm for one second. To calculate joules from volts, you typically need capacitance (in farads) as well. This tool is perfect for electronics engineers, students, and educators who want to quickly find stored energy in a capacitor or energy transferred by voltage. Just enter the voltage (V) and capacitance (F), and get the energy output in joules (J). Simple, accurate, and fast for any learning or professional need.
Sample Volts to Joules Canversion Table
| Voltage (V) | Capacitance (F) | Energy (J) |

| 5 | 0.001 | 0.0125 |
| 12 | 0.01 | 0.72 |
| 9 | 0.0022 | 0.0891 |
What is the formula to convert volts to joules?
J = 0.5 × C × V², where C is capacitance in farads and V is voltage in volts.
Can I calculate joules from volts without capacitance?
No, capacitance is required for accurate joules calculation using voltage.
What is a joule in electrical terms?
A joule is a unit of energy equal to the work done by one ampere passing through one ohm for one second.
What units are required for this calculator?
Voltage in volts and capacitance in farads.
Is this calculator useful for capacitor energy?
Yes, it's commonly used to calculate stored energy in capacitors.
Can I use microfarads or millifarads?
Yes, just convert them to farads: 1μF = 1e-6 F.
Does this calculator work for AC voltage?
It is generally used for DC circuits or peak AC values.
What is the energy if voltage is 10V and capacitance is 0.01F?
J = 0.5 × 0.01 × 10² = 0.5 Joules.
Can I use this for physics homework?
Yes, it's commonly used for electrical physics problems.
What happens if voltage is doubled?
Joules will increase by a factor of four, since energy is proportional to voltage squared.
