Question

what is ohm' s law and derive it

Answer 1

Ohm's law states that electric current is directly proportional to voltage and inversely proportional to resistance of the wire across two points.

Answer 2

Answer:

Step-by-step explanation:

Ohm's Law :-

It states that , on a constant temperature , the current  I , flowing through the electric circuit , is directly proportional to the potential difference V , across its ends.

 V ∝ I

 I ∝ V

V/ I = R , constant of proportionality

R = Resistance [ opposes flow of current ]

V  = IR 

R = V/I

I = V / R
