Question
Explain network, junction point (branch point) and loop.

Answer

Simple circuits can be easily understood by using ohm's law only.
"If the components of circuit like resistors, capacitors, inductors and electric cells are connected to each other in a very complex way, then such a circuit cannot be studied just by using ohm's law. Such a complex circuit is called a network."
Junction point (branch point) : The point in a network, where more than two conductors meet is called a junction point (or branch point)
Loop : A closed circuit formed by conductors is called loop.
