Electrical Network Terminology
Electrical Network is any arrangement of electrical energy sources, resistances, and other circuit elements like connecting wire, switch, and protection. There are two types of electric circuits DC circuit and Ac Circuit. There are different types of circuit parameters Resistance, Inductance, Capacitance, Inductance, and Conductance.
Resistance:
Resistance means the measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms. It is symbolized by the Greek letter omega (Ω). Resistance represents R.
Inductance:
Henry said the amount of inductance required to produce an e.m.f of 1 volt in a conductor when the current change in the conductor is at the rate of 1 Ampere per second. So we can say that inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. SI unit is inductance is Henry and it represents L.
There are two types of Inductance
1) Self-inductance
2)Mutual inductance
Conductance
Network Terminology
Node
The connection of two or more circuit parameters or circuit elements is called a node.
From the figure, e a, bc, and d are electric nodes.
Junction
If three or more circuit parameters are connected in a circuit, it is called a junction. The junction is clear from the fact that three circuit elements R1, R2, and L1 are joined at it.
Brunch
A special part of a network that lies between two nodes is called a branch.
e.g. Voltage source VS1 of the branch.
Mesh
Mesh is any closed path of an electrical network in which no other path exists.
In the figure abga, bcgb, cdgc, dfgd are each a mesh.
Loop
The path connecting two or more messes of an electric network is called a loop
E.g. abcga, bcdgb, cdfgc, dfgd.
Source:
Which device supplies electrical energy. Example: Battery, Generator.
Load
It is the electrical Circuit that utilizes electrical energy. Example: Motor, Heater, Lamp.
Electrical Network
Any arrangement of electrical energy sources, resistances, and other circuit elements is called an electrical network. There are different types of the electrical network like
Active Network:
An active element is one that supplies electrical energy to the circuit. Here Vs1 and Vs2 are the active elements because they supply energy to the circuit.
Passive Network:
A passive element receives electrical energy and then either convert it into heat or stores it in an electric field. Below the circuit diagram, there are passive elements, namely R1, R2, L1, and C1. These passive elements receive energy from the active elements and convert them into heat.
lumped network
In this network, the circuit elements like inductance, resistance, and capacitance can be physically separated and are lumped in an electrical network. Most electrical networks are lumped in nature. The best example of is lumped network is a transmission line.
Distributed network
In this network, the circuit elements like inductance, resistance, and capacitance cannot be physically separated and are distributed in an electrical network.
Linear network
In this network, the circuit elements like resistance, inductance, and capacitance are constant irrespective of the change in time, temperature, voltage, and current For such networks, a constant coefficient exists between the voltage and current.
Non-Linear Network
In this network, If the circuit elements like resistance, inductance, and capacitance change their value with the change in time, temperature, voltage, or current, then it is said to be a non-linear network.
Example: Diode, Transistor
Bilateral network
In a bilateral network , if the relation between the voltage and the current does not change in either direction of the electrical network, then it is said to be a bilateral network.
Example: Transmission line
