the symbol of current density is 'J'. & its unit is (Amp/m^2)
In general density is represented by the Greek symbol rho (ρ)
Density current is where a warm current floats on top of a cold current.
The current element is directly proportional to the current density. The current density is the electric current per unit area of cross section.
The force that makes electrons move is a voltage, or potential difference and both are measured in Volts. When electrons move, the rate of movement is current, measured in Amps. The amount of current is dependant on both the resistance in a circuit and the voltage. The higher the resistance, the lower the current. The higher the voltage, the greater the current. The symbol for voltage is "V" and confusingly, the symbol for current is "I". The unit of resistance is the Ohm with the symbol "R" or the Greek symbol for omega.
The symbol for electric current is I
Current density refers to the electric current per unit area of a given cross section.
No, trade winds and evaporation can cause a density current but not freezing.
Current density is unrelated to Ohm's Law.
why do density currents hapen?
the density of cesium is 1.93 and its atomic # is 55 symbol Cs
Density is the lower case greek letter rho.
