Current density is the amount of electrical current flowing in a unit of cross sectional area of that conductor. You'd look at the current flowing and the cross sectional area of the conductor and make a calculation from that. All you need do is decide on what unit of cross sectional area you wish to use. In wire, we usually use mils. Use the links below for more information.
Density current is the measure of the density of flow of a conserved charge

Is there a relation between Faraday's constant and current density?
i=F*sum(zi*Ci) where, i is the current density, F is Faradya's constant, zi is the velence of species i, Ci is the concentration
What is aconvection current?
A convection current is a natural flow or circulation of fluid due to a variation in its density due to temperature differences. As a fluid's temperature increases, its density reduces, and the fluid rises to be replaced by fluid at a lower temperature. Convection, together with conduction and radiation, is a method of heat transfer.
What does a conevection current mean?
Motion of a fluid (liquid or gas) caused by density changes caused by temperature changes.
What happems when frequency is changed and voltage and current remain unchanged?
In magnetic circuits, such as occur in transformers and motors, the flux density is inversely proportional to the frequency, so a drop in frequency could cause overheating through excessive flux density.
