A physics textbook for the 8th grade was analyzed, in particular the section on the interaction between electric current and magnetic field. The textbook i
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;...
