1.	21. State Ohm's law. How can it be verifiedexperimentally. Does it hold good under allconditions? Comment.
Answer» Ans :- Ohm's law states that at a constant temperature, current 'I' through a conductor between two points is directly proportional to the potential difference or voltage 'V', across the two points. That is, This constant is called as the resistance (R) of the conductor. Ohm'slaw show the relationship between potential difference and current, where as it states that potential difference is directly propotional to currentmathematical expression for ohm's law is VαI i.e., V=IR
