The concept of current division principle occurs in resistors connected
in parallel in a circuit. In a parallel circuit, the current which flows in
each of the branches is inversely proportional to the value of the resistance
in the branch. The value of current flowing through a branch reduces with
increase in the value of the resistance. The circuit below shows a network of
the resistors connected in parallel.
