Electrical Circuits

A simple Electric Circuit is a closed connection of Batteries, Resistors, Wires. An Electric circuit consist of voltage loops and current nodes. Simple circuits are categorized in two type:

Series Circuit: is a circuit that has only one pathway. There are no branches in the circuit, and hence the electricity can only travel in one route. In series circuits, current is constant, but the voltage is different, and adds to the total voltage.

Parallel Circuit: is a circuit with two or more paths. The current is spread along the various branches. The current in one branch will not be the same as in other branches (unless all the resistances are the same). In parallel circuits, the voltage is constant, but the current varies, and adds up to the total current in the circuit.
