# Ohm's law

### Ohm's law

In 1826, the relationship between the German scientist, Dr. George Simon Om, and the flow of current and current flowing through the direction of a conductor was expressed by a rule called 'Om Law'.

According to this rule, if there is no change in the physical condition (like heat) of the driver, then the ratio of the probability imposed on its ends and the current flows is fixed.
So if there is a probable variant on the crossing of the bark and the stream flowing in it, then according to the Om rule.

$\frac{V}{I}&space;=COSTANT$

According to the determinant definition, the ratio of 'V' / 'driver' to 'electrical resistance' is R

$\frac{V}{I}&space;=R$

In this way, according to the rule of Oh, unless the conduct of a conductor changes in heat and other physical conditions, the driver's resistance remains fixed even though the extent of the impact on the ends of the driver
.

Ohm's law is only true for metal movements
