What Is Statement Of Ohm's Law And Where Its Use?? 




There Is The All About The ohm's Law Like What Is Ohm's Law , How We Can Apply In The Electrical Circuit!! 





Statement of Ohm's law:

The Ohm's Law states that the ratio of potential difference(V) between any two point and The Current flowing between them is constant if tempreture is constant.

This ratio is turmed as resistance R.
V/I = constant = R Ohms.




Ohm's Law deals with the relationship between voltage and current in an ideal conductor.

This relationship states that: The Potential Difference (voltage) across an ideal conductor is proportional to the current through it.

The constant of proportionality is called the "Resistance", R.


Example, that we have a circuit with the potential of 1 volt, a current of 1 amp, and resistance of 1 ohm. ... The amount of water in the tank is defined as 1 volt and the “narrowness” (resistance to flow) of the hose is defined as 1 ohm.




The Ohm's law is not applicable to any non-linear device as diode, transistor, zener diodes etc.

Its applicable only to the linear device.




Coulomb's law 

Coulomb's law states that: The magnitude of the electrostatic force of attraction between two point Charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. The force is along the straight line joining them.
