Question

state ohm's law..and its mathematical representation

Answer 1

Hey friend ..!! here's your answer
_________________________

One volt of potential difference equal to curren (I) directly proportional to Resistance (R) . It remains the temprature same.The S.I unit of resistance is ohm.

Mathematical representation.

V = IR
I = V/R
R = V/I

Answer 2

Definition:-

At constant temp. the current flowing through a conductor is directly proportional to the p.d. (potential difference) across its ends.
=> "I" is the current flowing through a conductor and
"V" is the p.d. across its ends then according to OHM's law :-
"I" is directly proportional to"V"
=> I = V/R
=> V=IR


MATHEMATICALLY :-

R=V/I

* The ratio of p.d. across the ends of conduction to the amount of current flowing through it.

* The 1 resistance is the p.d. of 1 volt in a current when 1 A ( ampere) of current flows through it
=> 1 resistance= 1V/1A


refer to the picture above.......
