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.

Distinguish field theory and circuit theory?
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.
What does potential diffrence mean?
Potential Difference is the difference in electric potential energy per coulomb of charge at one point of a circuit compared to the charge at another point in a circuit. Potential difference, or voltage, is a way of describing the energy of an electric field without using test charges. In circuits, potential difference is the difference in voltage from one part of a circuit to another. It can also be described by ohms law where the Voltage=Current*Resistance In electrostatics, potential difference is the line integral of the electric field from one point to another with respect to distance.

Electric field between two parallel plates?
The question is too general. There are books dedicated to exactly this subject. Example:Boundary-layer theory By Hermann Schlichting, K. Gersten.

How does the composition of the inner and outer core explain this theory?
Dynamo theory is the idea that a magnetic field generator exists within the Earth's outer core. It is this generator that explains the difference between the inner and outer core.

What is the difference between a scientific theory and a hunch?
A hunch is unsubstantiated. Scientific theory is theory in which an idea or even a hunch has been thouroughly tested- thru a hypothesis, testing the hypothesis, and results based on the scientific method. It is supported by other experiments and generally accepted by professionals in the field
