Answer:

Liquids can be tested to check if they are good conductors of electricity. The free ends of a tester is dipped into liquid to be tested for the glowing of bulb. If the bulb glows, then it is good conductor and if the bulb does not glow, it is a poor conductor. All liquids are not good conductors of electricity.

Answer:

here is your answer

AIM- testing the electric conductivity of liquids.

MATERIALS REQUIRE take a LED,dry cell,metal pins,rubber cap of injection bottle and wires for making connection..

procedures set up an electric circuit see that two metal pins,pass through the cap should have a small gap(around 2mm) between them so that the pins are fairly closer but not touching each other the LED should not glow when pins are separated by the small distance.

now,jain the free ends of the pins together by pressing them for a movement and make sure that the LED glows release the pins the get separated and LED should not glow this becomes our tester we will use this tester to check the conductivity of liquids.........

fill the rubber caps with different liquids,one after another and in each case check whether the LED glows or not lets start with distilled water pour distilled water in the rubber cap till the two metal pins come in contact with not check the LED glows or not now lets check normal water.......repeat this procedure with other liquids like coconut oil,kerosene,lemon juice,mustard oil,sugar solution,etc...

note after testing each liquids carefully wipe and dry the caps and pins before filling in the next liquid....

OBSERVATION-you may have observed that in all those cases where the LED glows,its brightness (intensity) is not the same sometimes it may be brighter and some times it may be relatively dimmer the intensity of the glows of yes LED depends on the flow of the electric current through the circuit.

RESULT as result,although tee circuit is completed and the LED glows,due to weak current in cases of some of the liquids,tee intensity of glow would be lower compared to other liquids..........

hope this helped you
