3.Practical ELECTRIC TOOLS

 ELECTRIC TOOLS


Plier-:

*plie
r is used to joined two wire`s together and alsofor wire cutting and removing wire cover of it .

wire stripper-:

*It is use for wire cutting 

Line tester-;

*Before we touching any electrical wires we want to test with line tester after than we can touch it.

Hand drill machine-:

*drill machine is used for drilling in wall`s and wood and for patti fitting.

Hammer-:

*hammer is used for  patti fitting and for switch board fitting by hammering nail`s.

Screw driver-:

*It is used for tight screw .




 Multi meter-;
*Multi meter is used  for checking voltage in meter we can know about it is three phase or single phase .





                    CHARCOAL AND FIRE WOOD


Aim:- We have to measure the temperature of water while firing charcoal and firewood separetly. 
                                                 

Requirements:-Smoke less chula ,thermometer,wood (250 gm), charcoal (250 gm) and water (500 ml)

Procedure:-first we take wood (250 gm) and charcoal (250 gm)and water (500 ml) and take chula and we did only charcoal experiment we take charcoal 250 gm and put in to chula and we burn it with paper and small quantity of wood to burn charcoal and at half of the experiment we put the plate on  it and we taking record at every five minutes .

4.Practical JOINT`S

Image
    JOINT`S Aim:- exploring different types of wire joint`s          Requirement`s:-plier, stripper and wire.              procedure:-we saw different types of joints . 1) Union joint :-the wire are crossed positioned  to make along and twist or bend in each wire at one end of the wire is unrapped and then the other and four or five times around the straight position of each wire are pressed down as close as possible to the straight position of  the wire. 2) Married joint :- The married joints used for joining multi stand cables. The wire re-unstranded and then interlocked with the wire of the other cable and then married (Twist) together finally being soldered. 3) Simple joint :- simple joints used in house wiring and while doing simple wiring work. 4) Britania joint:- The britania joint is a from of electrical joined use for base over head wire where great tight ...

15.Practical Tripod stand

Image
Aim:  Learning about tripod stand. Requirements: Tripod stand U-shaped petti Compass olamba Ranging rod Paper Small nails  abilate  petti Procedure : First we go to the plane surface and we putted the tripod stand in one corner. Than we fix table on tripod stand next we take u-shaped petti we put at down ward nut bolts at middle and we measure the midpoint of table and we put a paper and at middle, we marked it by nailing at down ward nut bolts.I put volamba to U-shape petti and we put stone at the straight volumba then we take abilate patti measure it at the corner we put ranging rod straightly and we measure it like this and we take the measure rement of that. Formula :1cm=10cm                10cm=100cm               1mm=10mm then we assembled the line then we see there is no shape then sir told to make triangle in it and we take measure...
