If someone is found innocent of a crime, and then new evidence comes to light proving her guilt, which protection applies?

The protection is called double Jeopardy its a procedural defense that prevents an accused person from being tried a second time on the same or similar case. As described in the U.S Supreme Court in its unanimous decision  one of its earliest cases dealing with double jeopardy," the prohibition is not against being twice punished, but against being out twice in jeopardy".  

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.
