OHM' s law :-

Ohm's law is given by George Simon Ohm.
according to this law:-

the relation between electric current and potential difference is known as Ohm's law.

Ohm's law is valid only if temperature of conductor is constant or remains the same.

according to this law ;-

the electric current flowing in a conductor is directly proportional to the potential difference across the END of conductor.

here is a proof of Ohm's Law

1 ) electric current is directly proportional to potential difference

I directly proportional to V

and ,

V is directly proportional to I ( current )

V =I R

here R ( resistance ) is the proportionality. and.

V / I = R




Ohm's law can be started as the ratio of potential difference across the end of conductor overflowing current through its remain constant If temperature and other physical condition of conductor remains constant.






1 Ω is defined as:-
if the potential difference of 1 volt across the end of conductor makes a current of 1 AMPERE PASSES through conductor.





hope it helps you dear !!

thanks !!
