Farads to Joules Calculator
Convert capacitance from Farads (F) and voltage from Volts (V) to energy in Joules (J)
How to Convert Farads to Joules
Farads (F) cannot be directly converted to joules (J) with a simple numerical factor because farads measure capacitance and joules measure energy—different physical quantities. They’re related in a capacitor through the energy formula E = 0.5 * C * V², where voltage (V) is needed to connect them.
Farads to Joules Formula
Quick Trick: To find energy, use E = 0.5 * C * V²!
Understand the Conversion
The formula to calculate energy in joules from capacitance in farads is:
E = 0.5 * C * V²
Where:
- E is the energy in joules (J)
- C is the capacitance in farads (F)
- V is the voltage in volts (V)
To calculate the energy, multiply the capacitance by the square of the voltage, then multiply the result by 0.5.
What Do These Terms Really Mean?
Farad (F) – A Unit of Capacitance
Farads are a standard unit of capacitance. Here’s what you need to know:
- Used to measure a capacitor’s ability to store charge.
- 1 farad is the capacitance of a capacitor that stores one coulomb of charge at one volt.
Joule (J) – A Unit of Energy
Joules are a standard unit of energy. Here’s what you need to know:
- Used to measure energy, work, or heat.
- 1 joule is the energy transferred when a force of one newton moves an object one meter.
