Magnetic field

The science is always a benchmark The science is always a benchmark from which to begin to count the data size. For example, when measuring the temperature assumes that the level of zero, the so-called. Zero is the temperature at which the ice turns into water. In making the measurements of potentials for the zero level was adopted considered the degree of electrical charge the earth. As a result, the electric potential can be positive or negative in relation to land, depending on whether the guide will be stored in a positive electrical charges, or are negative. If a guide is electricity charged to the positive potential of A in relation to the land and another for the potential 2 in relation to the land, the difference of potentials of these guides will be the difference between algebraic. If these guides to connect with each other with wire, it Popsicle of the electric current from a higher potential, the guide of a lower potential. The flow of electricity will continue as long as no potential to catch up. The time needed to align the capabilities will be short-lived, as a result of which will have virtually no meaning. In order to practically use a current, you need to create conditions for the difference potentials remained stale.
