WIRE & CABLE
Varies types of wires.1.VIR wire:
It is called vulcanized insulation rubber wire. Copper & aluminum conductor are used in its. Rubber coating vulcanized on its. now single & double braided wires are mostly in a uses. But Its lower tensile strength,chamical reaction & bed insulation so its uses low in today.2. CTS & TRS wire:It is called crab tyre sheath wire & tuff rubber sheath wire. Hard & good rubber coating on copper wire in this wire. Its uses in house wiring & industrial wiring. It is used in a11kv.

3. Weather proof wire:No any weather reaction , in this types of wire. Because it has cotton breeding with water proof. But it is flammable so no in use now.
4. LC wire:It is called led covered wire. Led pipe on rubber insulation &its coating on conductor. It is very good in moisture condition but less tensile strength so low uses now.
5. MICC wire :It is called mineral insulated copper covered wire. In this types wire copper conductor coated with magnesium oxide. And After copper coating is coated on its. In case of moisture weather PVC coating (serving) is coated on its. It

Kirchhoff’s First law:“At each junction of currents, the sum of the incoming
current is equal to the sum of the outgoing currents.”If all inflowing currents have positive signs, then we
can state that, I1+I2=I3+I4+I5
+I1+I2-I3-I4-I5=0in the above example the sum of all the currents flowing
at the junction (node) is equal to zero.ΣI = 0
Kirchhoff’Second Law:“in closed circuits, the applied terminal voltage V is
equal to the sum of the voltage drop V1+V2 and so forth." If all the generated volt. Are taken as positive, and all the consumed voltage are taken as negative, then it can be stated that; in each closed circuit the sum of all voltage is equal to zero. ΣV = 0

Introduction Varies uses of megger
1) To measure insulation resistance of wire. 2) Testing of faults. 3) Testing of continuities of circuits. 4) To measure earth resistance .
Structure of meggerMegger is one type of a D.C. generator and used for
measurement of insulation resistance of cable and earth. It is rotate in 160 rpm with help of handle. It is generate about 500 volt. Scale of megger is in ohms range. Megger have two or three terminals, there are ear thing, ground and line.
Megger use as a earth tester.

FLUORESCENT LAMP
Principle of a discharge lamp:the basic principle of a gas discharge lamp is explained.
Gasses are normally poor conductors, especially at atmospheric & higher pressures, but application of suitable voltage( known as ignition voltage) between two electrodes in a sealed envelope containing gas at low pressure ionises the gas and current passes from one electrode to the other.
A glass shall with two electrodes apart is connected through lead in wires to the voltage source. The space within the shall is filled with low pressure vapor . When the voltage applied to the electrode is increase to a certain value , the gases inside gets ionise & start conducting when once the ionization take place & current is conducted from one to

The UV radiation can not be perceived by the human eye, certain phosphors have the property of emitting light in the visible spectrum when the phosphor is exposed to UV rays.
