Power is the ability to get others to do what you want, while authority is the right to exercise power. Authority is transformed from power through legitimacy. Legitimacy refers to the acceptance of an individual's right to wield power or authority, based on a set of norms, rules, or beliefs. When power is exercised in accordance with these norms or rules, it becomes legitimate, and the individual holding the power is seen as having the authority to do so. For example, a government may exercise power through laws and regulations that are based on the constitution, and when the government is seen as legitimate, the power it wields becomes authority.
