OHM LAW
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.
Mathematically, this current-voltage relationship can be written as, = V=IR
In the equation, the constant of proportionality, R is Resistance and has units of ohms, with symbol Ω.
The same formula can be rewritten in order to calculate the current and resistance respectively as follows: I=V/R AND R=V/I
Ohm’s law only holds true if the provided temperature and the other physical factors remain constant.
