4. A black from out to holder.s

• Series circuit                                              

1. A red from out to inputs of 3 switches.
2. Wires from switches outputs to holders.
3. A black from all holders to out.

Observation  :  

1) I observed the types of wire connection in separate circuit .

2) I saw neutral,fase,earthing and main.first i joint the yellow wire at swith at down word`s and same joint`s at three swithe`s 

3) And last swith at down word`s i take another wire to that and give that to bulb holder and give connection to the two bulb.

Plier-:

*plier 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 .
