it means no of charge present per unit volume of the electric field
there are two rules to succeed
1.never tell everything you know.
2.never tell you know everything.

It means total energy of a configuration having charges per unit volume .
I don't think there is any expression for that.Charge density has an expression.

i m sorry it means energy present per unit volume
the expression is u=U/Ad Ad is the volume
where U is the potential energy of the field
energy density of electric field of a parallel plate capacitor is u=1/2(epsilon0E2)
there are two rules to succeed
1.never tell everything you know.
2.never tell you know everything.
