What is the current density of the solution a/m2

Current density of solution a/m2 is given below

Step-by-step explanation:

Current density is the measure of current generated per unit surface area of electrode.

Eg: In microbial fuel cell/fuel cells, if you are using electrode with size of 5cm x 2cm and current produced is 200mA, then current density will be,

CD = Current / (projected area of electrode)

area of rectangle = LxB = 5cm x 2cm = 10cm2

CD = 200mA/10cm2

CD = 20mA/cm2

Your Current will be 200mA.

Current density will be 20mA/cm2.
