The requirements of the federal law that spells out the criteria for fair representative districts specifies that each must contain an equal number of what?

Citizens and mandates a census to determine the number of citizens and apportion seats to each state.

Explanation:

As it is been practiced in decades, this is a process of drawing boundaries for electoral and political districts in the US and is usually done every ten years after the census. The US constitution requires each Representative in Congress represent an equal number of citizens and mandates a census to determine the number of citizens and apportion seats to each state.

Redistricting procedures vary by state individual states have the responsibility of drawing legislative boundaries for congressional districts as well as for state legislative districts. In most states, the state legislature districts seats, usually subject to concurrence by the state governor. A few conduct redistricting through an independent or bipartisan commission in order to minimize the impact of partisan or legislative politics. A handful allow an independent commission to propose redistricting plans subject to approval by the state legislature.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
