Gibbs Free Energy Calculator - Thermodynamics Calculator

About This Tool:

Calculate Gibbs Free Energy of a thermodynamic system using this free Gibbs Free Energy online calculator tool.

What is Gibbs Free Energy:

In thermodynamics, Gibbs free energy is a thermodynamic potential that predicts process whether it will occur spontaneously at constant temperature and pressure.

Formula:

The Gibbs free energy is defined as:

G(p,T) = H - TS

where:

    U - internal energy
    p - pressure
    V - volume
    T - temperature
    S - entropy
    H - enthalpy

Gibbs Free Energy Calculator

Enthalpy (H) : joule per kelvin
Temperature (T) : kelvin
Entropy (S): joule per kelvin
Gibbs Free Energy : joule per kelvin

Capacitor Charge, Energy Calculator

Online electronic Capacitor Charge Energy Calculator calculates the charge of the capacitance and energy stored in a capacitor in Coulombs & Joules.

Capacitor Charge, Energy Calculator

Capacitance of the Capacitor (C) :
Voltage applied to the Capacitor (v):
 
Charge on the capacitor (Q): Coulombs
Energy stored on the capacitor (W): Joules


Formula:-
Capacitor Charge Q = C*V
Where, C = capacitance of the capacitor V = voltage applied to the capacitor

Energy stored W = ½ QV = ½ CV2
Where, W is the energy measured in Joules.

Capacitor Potential Energy Calculator

Capacitor Potential Energy Calculator. Calculates total electric potential energy(power) stored in a Capacitor. The maximum stored energy is essentially the integral of the charge with respect to voltage in a network.

The energy stored in a capacitor can be expressed as,

U = 1/2 * C * V²


Where,
  • U : electrostatic potential energy
  • C : capacitance
  • V : Potential Difference


                        Capacitance [C] :

            Potential Difference [V] : V

      Stored Potential Energy [P] : J
