The electricity flows <u><em>b) from high potential to low potential</em></u>
Explanation:
Electric current is the circulation of electrons through a conductive material. It originates by contacting two elements between which there is a potential difference. Then the electrical charges that constitute an electric current pass from a point that has greater electrical potential to another that has a lower potential. To permanently maintain that potential difference, also called voltage or voltage between the ends of the conductive material, a device called a generator (for example, batteries or batteries) is needed that takes the charges that reach one end and drives them to the other.
Then <u><em>the correct answer is b) from high potential to low potential</em></u>
Depends on what type of mirror that is. I am going to assume this is a plain mirror (from the phrase), which means the height and width of the object and image is exactly the same.
