Question

State ohms law how can it be experimentaly verified does it hold under all conditions

Answer 1

Here you go...

Answer:

(not from internet )

Ohm's law show the relationship between potential difference and current, where as it states that potential difference is directly propotional to current

mathematical expression for ohm's law is 

     V α I

     i.e., V=IR

 q2 answ:factors affecting resistence 

  - length [Rαl]

  - area of cross section [Rα1/A]

  - nature of material 

  - temparature [RαT]

Answer 2

Answer:

it

Explanation:

it states that electricity flowing through a conductor is directory proportional to the potential difference applied across its ends provided physical condition like temperature.

Condition:

temp. should remain constant.

Limitation:

temperature never remains constant.
