Here, is the current density, and is the electric field.
These reactions have 100% efficiency over a wide range of current density.
Using these results we have the current density to the surface due to the ions.
The Townsend avalanche can have a large range of current densities.
Less energy is required because of the lower current densities required.
The current density of the universe is observed to be very close to this critical value.
Unfortunately, critical current densities in these complexes are very small.
The electric field is then, the current density, and the current.
We assumed then that the electric field was proportional to the current density.
For example, current densities will have to be increased by more than a factor of 100 from values attained at present.
