Define network, junction (branch point), loop.

Explanation

`rArr` Simple electrical circuit can be analyzed by using Ohm.s law. When number of resistors, capacitors, Inductors and cells connected in complex way , then Ohm.s law is not sufficient .
In this condition Kirchhoff.s laws are useful.
`rArr` Junction ( Branch point) : In network, point at which two or more conductor meet is called junction or branch point.
`rArr` Loop : A closed path comprising of component is called Loop.
