A democracy where the people elect agents to represent them in political decision-making is called "Republic".
Republic is a Latin word which means "the public thing", and the idea behind is that the supreme power rests with the people and these people elect their representatives for political decision making. The power in such cases is not private or monarchial in nature and cannot be inherited by generations of rulers. 

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.
