 B^2
/ ( 2* μ* μ0)
W =  
 ε0* ε* E^2
/ 2
+ 
 B^2
/ ( 2* μ* μ0)
$$W$$ = $$\frac{\varepsilon0\cdot \varepsilon\cdot E^{2}}{2}+\frac{B^{2}}{2\cdot \mu\cdot \mu0}$$
W =  
 E^2* ε* ε0
/ 2
+ 
 B^2
/ 2/ μ/ μ0
$$W$$ = $$\frac{E^{2}\cdot \varepsilon\cdot \varepsilon0}{2}+\frac{B^{2}}{2\cdot \mu\cdot \mu0}$$
W =  0.5* E^2* ε* ε0+ 
 0.5* B^2
/ μ/ μ0
$$W$$ = $$0.5\cdot E^{2}\cdot \varepsilon\cdot \varepsilon0+\frac{0.5\cdot B^{2}}{\mu\cdot \mu0}$$
