Demonstratethat thelaw of electriccharge conservation, i.e.,grad. J = -del rho//del t, follows fromMaxwell's equactions. |

Answer» Solution :From the equction `CURL vec(H) - (del vec(D))/(del t) = vec(j)` we get on takingdivergence of both sides `- (del)/(del t)` DIV `vec(D) = di v vec(j)` But div `vec(D) = rho` and hence div `vec(j) + (del rho)/(del t) = 0` |
