current density

Current density is important to the design of electrical and electronic systems.

The current density of the universe is observed to be very close to this critical value.

Using these results we have the current density to the surface due to the ions.

This way, vertical information can be extracted from the current density images.

The electric field is then, the current density, and the current.

Unfortunately, critical current densities in these complexes are very small.

The Townsend avalanche can have a large range of current densities.

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.

In semiconductors, the maximum current density is given by the manufacturer.

Less energy is required because of the lower current densities required.

Therefore, the current density decreases and the differential resistance is negative.

The voltage increases with increasing current density at the electrodes.

A more fundamental approach to calculation of current density is based upon:

It is a real vector, like electric current density.

Case 2: The proportionality between the current density and the magnetic field is a function of position.

Such devices have the advantages of both insulated gates and higher current density.

However, attempts to derive meaningful current density values will usually or always fail.

Some superconductors quench directly in response to a high current density.

The current density might be too low in some areas, and too strong in others.

Heating is usually greatest where the current density is highest.

The majority of the electrode's energy is concentrated at the ends due to the current density.

This reduces the effective area for current and increases the local current density.

These reactions have 100% efficiency over a wide range of current density.

This ongoing current in both directions is called the exchange current density.
