Difference between field theory and circuit theory?
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.
How would theory distinguish a scientific theory from a scientific law?
By not doing nothing

What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
How can you experimentally distinguish an electric field from a gravitational field?
Introduce two opposite charged objects one AT A TIME and if they move IN THE SAME DIRECTION, they are in a gravitational field, if they move IN DIFFERENT direction they are in an electric field.

Distinguish between optimum theory and malthusian theory?
Optimum theory proposes that there is an ideal population size that maximizes societal welfare and economic efficiency, whereas Malthusian theory posits that population growth will outstrip resources leading to famine and suffering unless controlled by preventive checks (like war, disease, or lack of resources) or positive checks (like famine, disease, or war). Optimum theory focuses on the balance between population and resources for societal well-being, while Malthusian theory highlights the consequences of unchecked population growth.
