Question

what is current density?​

Answer 1

Answer:

$hey \: mate \: here \: is \: \: ur \: answer$

current density is a measure of density of an electric current.It is defined as a vector whose magnitude is the electric current per cross sectional area. In SI units, the current density is measured in amperes per square meter.

Hope this helps.....

Answer 2

Hey there!

Electric Current Density:

Electric current density is defined as a vector magnitude that has units of electric current per unit area. It's S.I unit is ampere/meter²(A/m²) with dimensional formula A L⁻².

Relation Between Electric Current and Current Density:

$\boxed{\displaystyle I = \int_A j\cdotp d\bold A}$

where,

I = Electric Current in Ampere.

j = Current density

S = Area
