Question

state ohm's law. define resistance of the one ohm.​

Answer 1

Explanation:

HEY MATE ...

➞Ohm’s law states the relationship between electric current and potential difference. The current that flows through most conductors is directly proportional to the voltage applied to it. Georg Simon Ohm, a German physicist was the first to verify Ohm’s law experimentally.

➞One of the most basic and important laws of electric circuits is Ohm’s law.

➞Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature remain constant.

Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature remain constant.Mathematically, this current-voltage relationship can be written as,

V = I .R

➞ In the equation, the constant of proportionality, R is Resistance and has units of ohms, with symbol Ω.

➞ Ohm is defined as the resistance of a conductor with a potential difference of 1 volt applied to the ends through which 1-ampere current flows.

Ohms is the SI unit of electrical resistance.

Answer 2

$\large \green{ \fcolorbox{gray}{black}{ ☑ \: \textbf{Verified \: answer}}}$

According to Ohm's law,

Current flowing in a conductor is directly proportional to the potential difference applied across to its ends at constant temperature & physical conditions.

So, According to the definition

V ∝ I

V/I = constant

Put the constant as “r” which indicates the resistance of the conductor.

R = V/I

V = IR

Where

I = current flowing in the conductor

V = potential difference applied across the conductor

R = resistance of the conductor

Unit of Resistance is called omega (Ω)
