The electrical component (resister, capacitor, inductor and supply sources) is connected in circuit in what ever manner i.e series or parallel is called electrical network.
It is those circuits which consist of many parameters (resister, inductor etc) and these parameters are connected in such a manners that don't solve easily by ohm law. When use ohm's law for the solution of circuit so it's required a lot of equation so we solve these circuits by different theorems. These circuits may be AC or DC.
Circuit is a close conducting, which allow current to pass or intending to pass pith the circuit.
Such circuits which not complete the path and its external resistance is infinite and zero current.
Such circuits, which provide shortest path to complete the circuit (before the load). It's resistance is zero and current is infinite
PARAMETERS OR CONSTANT
The different element from which an electric circuit are making is parameters or constant. i-c resistance, inductance and capacitance.
Such circuit whose parameters do not change and remain constant with voltage or current is called linear circuit.
Such circuit whose parameter are change with voltage or current and do not remain constant is called non-linear circuit.
This is those circuit to which we apply the supply from only one side or they pass current from one side and from the other side they just behave like open circuit. i-e diode, which is normally used for rectification (conversion from AC to DC) process.
This is that type of circuit, which pass the current from both side, OR they work in proper way when current is applied to it (but at a time from one side). i-e transmission line etc.
Appoint in a circuit which connect two or more than two circuit elements together is called node.
Node is a point in a circuit from which current is distributed in two or more than two paths.
The path b/w two junctions is called branch.
A close path in a circuit, which do not encount any component more than one time.
It is a component, which do not have any loop in it. OR Mesh is a loop, which has no loop within it.
