Distinguish field theory and circuit theory?

Answer 1

circuit theory:

1.this analysis is oriented by its own.

2.applicable only for portion of RF range.

3.the dependent and independent parameters,I and V are directly obtained for the given circuit.

4.parameters of medium are not involved.

5.laplace transform is employed.

field theory:

1.envolved from transmission theory.

2.beyond RF range.

3.not directly through E and H.

4.parameter of medium are involved in the analysis.

5.maxwell equqtion is employed.

Answer 2

Field theory deals with the study of electromagnetic fields and their interactions in space using differential equations, while circuit theory is a simplified approach that focuses on analyzing electrical circuits using basic circuit elements like resistors, capacitors, and inductors. Field theory provides a more comprehensive understanding of the physical phenomena involved, while circuit theory is more practical for analyzing and designing electronic systems.
