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.
Circuit Theory: As the name suggests, circuit theory deals with electrical circuit. An engineer can predict the performance of complicated electrical networks with the help of circuit theory. But this theory has certain limitations like :It cannot be applied in free space.It is useful only at low frequencies.This theory is unsuccessful in explaining the radiation of electromagnetic waves into space in radio communications.It cannot be used to analyse or design a complete communication system. Example: Radio Communication System.Electromagnetic Field Theory. Although electromagnetic Field Theory (EMFT) is complex in comparison with circuit theory but EMFT is simplified by using appropriate mathematics. This theory deals with E and H vectors, whereas circuit theory deals with voltages and currents.This theory has following advantages in comparison to circuit theory:It is also applicable in free space.It is useful at all frequencies, particularly at high frequencies,The radiation effect can be considered.This theory can be used to analyse or design a complete communication system. Example: Wireless Communication, Radio Communication.
Some recommended quantum field theory books for beginners include "Quantum Field Theory for the Gifted Amateur" by Lancaster and Blundell, "Quantum Field Theory Demystified" by David McMahon, and "Quantum Field Theory in a Nutshell" by A. Zee.
One highly recommended quantum field theory book for beginners is "Quantum Field Theory for the Gifted Amateur" by Lancaster and Blundell.
The electric field in a circuit is directly related to the current flowing through it. The electric field is what drives the flow of electric charge, which is the current. In other words, the presence of an electric field is necessary for current to flow in a circuit.

Perpendicular to the circuit.
Mutual inductance is the basic theory of the coupled circuits.
A circuit is a path for charge particles -- it conducts current. An inductor, a circuit component, generates a magnetic field, when an AC is on. ======================
