Question

what is current density? establish the vector form of ohm's law.​

Answer 1

Explanation:

The vector form of Ohm’s law is used in electromagnetics and material science. The vector form is given as,

\bar{J} = \sigma \bar{E}

J

ˉ

=σ

E

ˉ

Where,

– represents vector

\bar{J}

J

ˉ

is the current density, \bar{E}

E

ˉ

is the electric field and σ is conductivity.
