    Graduate Is the Uniqueness Theorem in EM Always Proven by Contradiction?

    it isn't that tough but i was trying an alternative i get it so i have to integrate over each possible surface thus needing the charge density at each surface

    Graduate Is the Uniqueness Theorem in EM Always Proven by Contradiction?

    but what i tried to prove was without these conditions so what is wrong with my proof

    Graduate Is the Uniqueness Theorem in EM Always Proven by Contradiction?

    isnt the field in any given volume always uniquely determined to prove by contradiction assume E1 and E2 div(E1)=charge density/epsilon 0 =div(E 2) by fundamental theorem of divergences integral of E1.da = integral of E2.da over entire surface thus E1=E2 then why does griffith in his...
