Document Summary
Ex ) uniformly charged cylinder , p , radius - * e inside a t for uniformly charged systems. * f outside , line a l z. Conservation fields: av = - sri" di. E = gradient : f is a vector operator grad. " del " that acts on scalar functions . # if = partial derivatives take derivative with respect to x , leave y , t constant. Ex ) fl x , y , t ) X - y z t 2x "t " 2 = ft = y t 2x t 22-2. X y t 2x ( zz ) o. = # i + fyi + # k. Tol to = electric potential ( same as the v ) Iii + fyi -if i t ez i. Note : sv so if path goes against e" along e" Dv so if path goes field lines field lines ai.
