What is the relationship between current density and electrode size?
A) Current density is directly proportional to electrode size.
B) Density depends on the intensity of the current and not electrode size.
C) For every square centimeter of electrode there is a twofold increase in density.
D) Current density is inversely proportional to electrode size.

Question

Quizplus · Accepted Answer

Current density is inversely proportional to electrode size. This is because as the electrode size increases, the total surface area for the current to flow through also increases, causing a decrease in current density. The opposite is true for smaller electrodes, where the surface area is limited, causing an increase in current density.
