  • @nabachetia8824
    @nabachetia8824 3 года назад +2

    sir........there are two types of ohm law experiment in our practical book . They are -
    1)..To observe the variation of potential different (V) accross a given resistance by changing current (I) through it. Draw I - V graph and find the value of given resistance from it.
    2)..To construct a potential divider with the help of a rheostat and a battery and use it to verify ohms law.
    Sir how can I do both experiment? Tomorrow is my exam. Plz sir reply
