→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.
