For description of the ramified electric circuit the Lagrange- Maxwell equations are used, which are formulated from electro-mechanics analogies "force - tension" and "force - current". The statement and analysis of problems about functioning of piezoelectric generators and piezoelectric vibrator in an electric circuit at different conditions are done. It is developed and realized the of finite element algorithm for calculation of axisymmetric electroelastic deformation of piezoelectric cylinder bodies with axial and radial polarizations at the forced steady-state harmonic vibrations.
