Aim: - working and connection of tube

light, and troubleshooting method…

Tools: - Tester, screw driver, series testing lamp…

Material: - 1.50 mm  wire, Insulator tape, Ballast starter, tube holder…

Procedure: - 1) we brought a tube light which not working.

2) we test the supply wire of tube light.

3) we test a tube light using a series lamp.

4) we checked the connection reoffering from a circuit diagram.

5) we trouble shouted the tube light and ballast.

 Observation: - 1) we observe that the tube light was successfully passed the trouble shooting test.

2) secondly we checked the started it was working in a good condition.

3) thirdly we checked the ballast it was working…

Conclusion: - after 1 hour of work we concluded that the problem was with the faulty wiring…

                                                  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 

                     ripod stand 

  T

Aim: Learning about tripod stand.

Requirements:

.Tripod stand

1. U-shaped petti
2. Compass
3. olamba
4. Ranging rod
5. Paper
6. Small nails 
7. 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 measurement of all, sir give each one triangle.

Observation:

I measure the measurements that goes wrong, then I recognised my mistake then i calculate correctly
