							limitation:-
(1)KCL and KVL both depend on thelumped element modelbeing applicable to the circuit in question. When the model is not applicable, the laws do not apply.
2)kcl assumes that charge flow from one end to the other end of the conductor.but this is not valid for high frequency ac circuits.
(3)kcl which is based on the assumption that the total charge in a region remains constant.but it is conserved at a point not region where charge density changes.
(3)for high frequence ac voltage there is always change in magnetic field in a closed loop.it contradicts that line integral of magnetic field around a closed loop is zero
