In the federal system how is sovereign power divided among state and federal laws and constitutions?

In the federal system of the United States, sovereign power is divided between the national and state governments, with each having its own laws and constitution. The U.S. Constitution establishes federal law as the supreme law of the land, meaning it takes precedence over state laws when there is a conflict. States have the power to enact and enforce their own laws and constitutions, provided they do not contradict Federal Laws. This division allows for a balance of power and local governance while maintaining a unified national framework.
