W =

ε* ε0* E^²* S* d

/ 2

$W$ = $\frac{\varepsilon\cdot \varepsilon0\cdot E^{2}\cdot S\cdot d}{2}$

W =

E^²* S* d* ε* ε0

/ 2

$W$ = $\frac{E^{2}\cdot S\cdot d\cdot \varepsilon\cdot \varepsilon0}{2}$

W = 0.5* E^²* S* d* ε* ε0 $W$ = $0.5\cdot E^{2}\cdot S\cdot d\cdot \varepsilon\cdot \varepsilon0$
