| In short, they are similar to electric charge, isospin, and all the other internal quantum numbers of elementary particles. |
| Electrical conduction is the net motion of electric charge, and it cannot take place without the motion of matter on some scale. |
| The accumulation of excessive electric charge in dielectric insulation is extremely rare, but when it does occur, it is often catastrophic. |
| If the distribution of moving electric charge is not symmetric, the magnetic field will also be unsymmetric. |
| The boundaries between grains act like barriers to electric charge carriers, impeding the flow of current. |
| The film measures the compression force, which is seen in the form of the electric charge of opposite surfaces. |
