A second limitation of the current-carrying capacity is caused by the ohmic bulk resistance of the electrodes themselves.

Below this frequency the characteristic impedance rapidly rises and becomes more and more dominated by the ohmic resistance of the cable as the frequency falls.

Power absorbed by the ohmic resistance becomes waste heat, and that absorbed by the radiation resistance becomes radiated electromagnetic energy.

More general boundary conditions modelling ohmic contacts and insulating segments are admitted on the 'diffusion time scale'. As the core temperature rises, so does its resistivity and therefore the ohmic heating rate escalates. Since the skin depth greatly exceeds the wire radius, ohmic heating of the wire is at first volumetric. The decrease recover s slowly and the increase dies off exponentially due to the ohmic heating. One reason for this is that both authors show a strange reluctance to mention entropy and to relate its creation to heat transfer and viscous and ohmic dissipation. Taylor's relaxation requires turbulence; it produces reconnection of the field lines and local ohmic dissipation, breaking the invariance of the differential magnetic helicities. Ohmic heating increases for thickness lower than, approximately, 150 mm, which is consistent with the penetration of the fields in the target. Actual gain will be slightly lower due to ohmic losses.

The largest share of these losses in larger capacitors is usually the frequency dependent ohmic dielectric losses.
