Physics project

  1. Dec 3, 2003 #1
    I am a student of 12 grade and I need to prepare an investigatory project in physics for my exams.

    My teacher has suggested me to make a project on electrical conductance of different liquid solutions, like milk, fruit juices, etc.

    It would be geat if you can tell me what should I specifically do, like whether I should find the e.m.f produced by cells using diffeent liquids as electrolytes, or should I check the resistance of the solutions, or if you can suggest something better which would make this project more interesting and different from the other projects.

    I would really be greatful if you can help me out .

    Conductivity is the reciprocal of resistivity, so you can measure the resistance (from which resistivity and thus conductivity can be inferred).
