# Conductance Charged Box

A box with thick and conductive sides with dimensions: Lx, Ly, Lz- while LZ>>Lx,Ly. The long dimension of the box [Lz] can be viewed as infinite so Phi(x,y,z)=Phi(x,y)

Given that:

• Phi(0,y)=-Phi(Lx,y)=1V
• Phi(x,0)=Phi(x,Ly)=0
• Lx=Ly=1cm

I want to calculate (after stabilization):

1. The electric potential
2. The electric field
3. Distribution of electrical charge on the sides of the box

I know that the Laplace equation must be used, but I do not understand how to do it ... Can anyone help?
