# Energy stored in electric field

I know that energy stored in electric field / unit volume = 1/2 ε E2

so can I say that for any configuration calculating ∫ ½ ε E2 over whole space - gives me the potential energy stored stored in the system

for instance
for →
Q1 °

° Q2 ...separated by distance 'd'

∫ ½ ε E2 over whole space = KQ1Q2 / d

Please check your final equation. You integrated energy density over space and got a force!

Oh ! I meant interacting potential energy

have corrected that !

?

Say something

If you still have questions, you should ask them, instead of barking orders at us.

i have my question at the top !

nobody solved it so , i could have counter question

by the way sorry if was curt any way  ## 1. What is the definition of energy stored in electric field?

Energy stored in electric field refers to the potential energy that exists in the space surrounding an electrically charged object. It is a form of energy that is created when charges are separated, creating an electric field around the object.

## 2. How is energy stored in electric field calculated?

The energy stored in electric field can be calculated using the formula E = 1/2 * Q * V, where E is the energy stored, Q is the amount of charge and V is the electric potential.

## 3. What factors affect the amount of energy stored in an electric field?

The amount of energy stored in an electric field is affected by the amount of charge present, the distance between the charges, and the dielectric constant of the material between the charges.

## 4. What is the unit of measurement for energy stored in electric field?

The unit of measurement for energy stored in electric field is joules (J) in the SI system. In some cases, it may also be measured in electron volts (eV).

## 5. How is energy stored in electric field used in practical applications?

Energy stored in electric field is used in a variety of practical applications, such as in batteries, capacitors, and electric motors. It is also used in the transmission and distribution of electricity to power homes and businesses.
