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.
