What is ohm'Law? its application.uses in daily life?

Answer 1

Ohm's law applies to electrical circuits; it states that the current through a conductor between two points is directly proportional to the potential difference (i.e. voltage drop or voltage) across the two points, and inversely proportional to the resistance between them.

The mathematical equation that describes this relationship is:

I = V / R

where I is the current in amperes, V is the potential difference in volts,and R is a circuit parameter called the resistance (measured in ohms, also equivalent to volts per ampere). The potential difference is also known as the voltage drop, and is sometimes denoted by U, E or emf (electromotive force) instead of V.[1] I is from the German Intensität meaning "intensity".

Ohm's law applies to conductors whose resistance is (substantially) independent of the applied voltage (or equivalently the injected current). That is, Ohm's law only applies to the linear portion of the I vs. V curve centered around the origin. The equation is too simple to encompass devices described by a more complicated I vs. V relationship.

Answer 2

ohm's law - voltage across any conductor at a given atmospheric conditions is directly proportional to the current through it.

application - to find resistance of any conductor.
