In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.
