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.
Answer:
0,05
Step-by-step explanation:
Answer:
A square has 4 sides with equal length.
So the perimeter of a square is equal to 4 times the length of one side.
Now, suppose that we know that the length of one side of the garden is x.
Then the total length of the fence that surrounds the square is:
L = 4*x.
Now let's define proportional quantities:
x and y are proportional quantities if:
x = k*y
where k is a constant of proportionality.
In the case of our problem, we have a relation between L (total length of the fence) and x (length of one side of the garden)
L = 4*x
This is a proportional relation, and 4 is the constant of proportionality.
