6.Practical motor starter


Aim-: working and connection of a motor starter.
Requirements-: Tester, series lamp, copper wires.
Procedure-:
1) We look a mechanical starter from the artificial pond.
2) We opened it separated the parts and studied them carefully.
3)We checked the no of volt coil on the series lamp.
4)We brushed the contractor as a carbon residue forms after long time of use.
5)We saw the thermal relay that contains a bio-metallic strips.
Observation-; while testing the no of volt of coil we saw that when we passed the current through the no of volt coil turned in to electromagnetic.
Conclusion-: We concluded that we can use a mcb instead of a motor starter

    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...
