Good question! The difference is where they come from. Rules are guidelines and instructions for action, and are created to manage behavior within an organization or country. They are like written principles. Meanwhile, regulations are legal rules made in addition to the laws in a country. They are legally-binding. Thus, a rule can be an instruction given by a company or organization, whereas a regulation is a rule that is given by the state. Ex: There are some internal rules to learn within this company. Ex: The government is implementing new pandemic regulations.
