Converting an equation into weak form

Please login with a confirmed email address before reporting spam

The following equation describe the current densities of electrons and holes in a semiconductor.

(1)

(2)

(3)

(4)

(5)

The variables are J_n, J_p, n, p and E.

rho is charge density which is equal to .

G and R are function of generation and recombination.

I would like to change it into a weak form and use the pde interface . However, I do not know how to convert (3) and (5) into weak forms. Any suggestion to convert them? Thanks.
