State and explain ohm's law - Ohm’s law and resistance - eSaral

Hey, do you want to learn about How to state and explain ohm's law? If yes. Then keep reading. Ohm’s Law: If the physical state i.e. temperature, nature of the material, and dimensions of a conductor remain unchanged then the ratio of the potential difference applied across its ends to the current flowing through it remains constant. $V \propto I$ Or $\mathrm{V}=\mathrm{I} \mathrm{R}$ where $R=\frac{V}{I}$ is resistance of conductor. $I=n$ e $A v_{d}$ $=n$ e $A \frac{e E}{m} \tau=\left(\frac{n e...
