8. Write an activity to test electric conductancy in materials.
Answers
Explanation:
Connect the positive side of your power pack to the bulb holder and another wire to the other side of the bulb holder. Your conductivity tester is now ready to be used. ( ...
Gather different household items to determine if they conduct electricity. ...
Touch the ends of wires to the different objects.
The most effective electrical conductors are:
Silver.
Gold.
Copper.
Aluminum.
Mercury.
Steel.
Iron.
Seawater.
Answer:
Aim:- to test various liquids for their electrical conductivity.
Materials:- cell , bulb , wire , switch , and a beaker with water solution.
Procedure:- adjust the tester using two cell, switch, wire and bulb .
NOW, take normal water in small beaker or glass bowl and dip the end of a tester in it and watch the bulb glows this shows normal water is a good conductor of electricity you will notice the bulb glow faintly. when bulb replaced by a LED ( Light Emitting Diode ) LED glows when it has weak electric current flows.
Observation:- use other liquid or what does such as lemon juice, soda water, salt solution, Honey, kerosene oil, and distilled water in place of normal water to test other conductivity.
