so that if they enter a certain volume at some point, they must also leave that volume. In this respect, a magnetic field is quite different from anelectric field. Electric field lines can begin and end on a charge, but no equivalent magnetic charge has been found in spite of many searc...
Similarly, if we use the symbol $$ A $$ for the surface area of a cylinder and $$ V $$ for its volume, then [A] = L2 and [V] = L3. If we use the symbol $$ m $$ for the mass of the cylinder and $$ \rho $$ for the density of the material from which the cylinder ...
The shaded segment has a volume , so that the number of free charges in it is nAx. The charge ΔQ in this segment is thus qnAx, where q is the amount of charge on each carrier. (Recall that for electrons, q is −1.60 × 10−19 C.) Current is charge moved per unit time;...
