there will be current that isn't carried by the current carrying conductors
a magnetic field
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.

Ohm's law is a linear approximation for the voltage versus current across a conductor. This approximation works very well for good conductors (like metals) as well as poor conductors (like wood), but not very well for semi-conductors (like Silicon).
The requirements for equipment grounding conductors specified in NEC 300.4 include ensuring they are continuous, securely connected, and sized according to the current-carrying conductors.
Bundled conductors have a higher current carrying capacity compared to a single conductor of the same total cross-sectional area, due to improved heat dissipation. This is because the proximity of the conductors allows for more efficient cooling and reduces the overall resistance.
The ground wire in an 8/2 with ground cable may be smaller because it is typically used solely for safety grounding purposes, rather than for handling electrical current like the other conductors. This design allows for adequate grounding while saving space and reducing material costs.
Capacitance exists between any two conductors, current carrying or not.
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
The grounding conductor size chart provides information on the recommended size of the grounding conductor based on the type of electrical system and the maximum fault current that could occur.

The equipment grounding conductor chart provides information about the size of the conductor needed to safely ground electrical equipment based on the current rating of the circuit.

There should be at least 2 meg-ohms between the current carrying conductors and between current carrying conductors and ground.
How deep is the box? (Need to know the volume of the box). It is 2.25 cu in per 12AWG conductor, and it does not matter if it carries current or not.
