What is electrical resistance and types of electrical resistance

Explanation:

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). ... Insulators: Materials that present high resistance and restrict the flow of electrons. The measuring unit of the electric resistance is the Ohm, The ohm is the resistance between two points of the conductor when the constant potential difference of 1 volt applied to these points, It produces the current of 1 ampere in the conductor, Types of electric resistance are the constant (fixed) resistance,

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
