n a power system different buses are identified to load flow studies. Buses in power system has associated with four different parameters such active power, reactive power, bus voltage, load angle.
It is known as accuracy and precision in the instrumentation are more important characteristics in an measurement.
1.Write suitable sources for direct current supply
Dry cells, batteries. DC generators are providing direct current supply to circuits

A half wave bridge rectifier is an electronic circuit which allows unidirectional current to flow through load during only one-half period of a complete one input AC cycle.
Rectifier is an electronic device , which converts alternating current supply into direct current supply with help of diode .
Induction motors are very popular in industries and commercial application nowadays. Induction motors are commonly working using alternating current supply.
Kirchhoff’s law is most useful for formulating network equation. This law can be used where network cannot be simplified by series parallel resistance equation. Kirchhoff’s works on based on analysis method to solve electrical networks.
An Instrumentation system need various element for its proper function from read the physical quantity to measure quantity observed by observer or end user.
Electrical sources in a very important component in an electrical network. It is responsible to deliver required electrical energy to networks. A electrical networks contains several kind of sources. Sources used in an electrical network either dependent or independent.
The electricity flow from one place to another place with respect to time said as electric current. According to its nature of flow through a medium, it can be classified into two categories,
There are few materials which conductivity is around 10-4 ohm-m to 0.5 Ohm-m at normal ambient temperature. But materials are also having resistivity in this range. But a very important criteria that actual semiconductor materials are negative temperature co-efficient of resistance and act as insulator in absolute 0°K temperature.
ntrinsic semi-conductor is chemically pure and no doped using any impurities. It is a single metal piece either silicon or germanium. All intrinsic semiconductors are obeying solid metals energy bond diagram. In an intrinsic semiconductor free electrons are almost equal to no of holes.
o connect resistors in parallel connection one end of the all resistors connected together as same as another end of those resistors are connected together. A source connected between these both junction to deliver current to it. In figure R1, R2,R3 resistors one end (A) connected which further connected with positive terminal of the source.
Semiconductor is a material which conducting state is in between conductor and insulator. A semiconductor offer resistance to flow of electrons about 1×10-7 to 0.5 x 10-3 Ohm(Ω).
