Question

how to derive ohm's law​

Answer 1

Answer:

Current is directly proportional to potential difference. I४v. Therefore V४I . V= IR. R is constant until temperature remain constant

Explanation:

Answer 2

Answer:

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
