Capacitor Energy Calculator, formula, Calculation with EXmaple

Capacitor Energy Calculator :

Enter the Capacity (C) in farads(F), Voltage (V) in volts (V), Stored charge (Q) in C, and you get the Stored energy (E) in joules(J).

Capacitor Energy Calculator

Capacitor Energy Formula :

Capacitor Energy formula is the energy E(j) in joules is equal to the one divided by two and multiply the capacitance C(f) in farad and multiply the voltage V2(v) in volts. Hence the capacitor Energy formula can be written as

E(j)= ½ *C(f) * V2(v)

Derivation:

If you want to estimate the Energy E-stored in a capacitor having capacitance c and Applied voltage then it is given by the equation

E=1/2 * C* V2

You can rewrite this equation by applying the bastic capacitance formula

C=  Q * v

To get the other analogous form of capacitance equation i.e E=1/2 * Q2 / c

Or  E=1/2 * Q *V

Example:1

Calculate the energy stored in it? In a capacitance of a capacitor is  80 F charged to potential of 250 v.

Answer:

Given that

Capacitance = 80 F

Applied voltage = 250V

We know the formula for Energy stored E = ½ * c * V2

E= ½ * 80 *202

E=16000.0 joules

Example:2

Calculate the energy stored in it? In a capacitance of a capacitor is  75  F charged to potential of 98  v.

Answer:

Given that

Capacitance = 75 F

Applied voltage = 98 V

We know the formula for Energy stored E = ½ * c * V2

E= ½ * 75 *982

E=360150.0 joules
