Answer:
Materials chemistry
Step-by-step explanation:
The branch of chemistry that is responsible for studying how materials conduct electricity, is the chemistry of materials, and within this, which studies the electrical conductivity of materials.
When a substance is capable of conducting electrical current, it means that it is capable of transporting electrons. Basically there are two types of electrical conductors: metallic conductors, also called electronic conductors and electrolytes, which are ionic conductors.
In electrolytes, the electric current can circulate thanks to the ions dissolved in it, which are the ones that transport the electrons from one electrode to the other, and thus conduct the current. The electrical conductivity of an electrolyte can be defined as its ability to transmit an electric current. The conductivity will depend in this case on the amount of dissolved ions in it, on the charge and motility of these ions, and on the viscosity of the medium in which they are dissolved. If the medium were water, we have to reduce its viscosity with the temperature, so that the electrical conductivity will increase in the electrolytes whose solvent is water, as the temperature rises.
