Abstract

Have been conducted theoretical calculations by using a simple electric circuit Poynting vector. Simple electric circuit consists of a voltage source with two identical resistors connected in series. It is assumed that the circuit is a circular circuit, and the wires are made of metal and the dimensions of the battery is negligible. The distribution of surface charge, the electrostatic field, and the steady flow along the wires produces a constant magnetic field. Earlier studies of the Poynting vector and the rate of flow of energy considered only idealized geometries in which the Poynting vector was confined to the space within the circuit. But in more realistic cases the Poynting vector is nonzero outside as well as inside the circuit. This situation is obtained by using the Poynting vector as the integral of the results of the dot product of two vectors ........., that the multiplication of electric and magnetic fields along the wire produces energy equal to the potential difference at that point ..... and .......multiplied by incoming current ...... are calculated analytically to prove the existence of a flow of energy, in order to obtain the total power generated by the battery is equal to the energy that flows into the cable per unit time.
