Question

state ohm s law . how can it be verified experimentally ? does it hold good under all conditions ? comment . please answer quickly...

Answer 1

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

Answer 2

Explanation:

Ohm's Law: At constant temperature, potential difference across a conductor is directly proportional to electric current passing through it. If V is the potential difference and is electric current, then as per Ohm's law:
