Hint: Ohm’s law is one of the most basic and important laws of electric circuits. First we will define or state the Ohm’s Law and then we will formulate each of the components of Ohm’s Law equation. And also discuss the implementation with an example.
Complete answer:
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. Or, it states that electric current is directly proportional to its potential difference with the constant temperature.Mathematically, the relationship between resistance, voltage and electric current can be written as Ohm’s as Ohm’s Law equation:
$R = \dfrac{V}{I}$ ,
In the equation, R is Resistance and has units of ohms, with symbol $\Omega $ .
From the above equation, we can formulate both Voltage and Electric current as well:
$V = I.R$ and
$I = \dfrac{V}{R}$
Ohm’s law only holds true if the provided temperature and the other physical factors remain constant. In specific parts, expanding the current raises the temperature. An illustration of this is the fiber of a light, wherein the temperature ascends as the current is increased. For this situation, Ohm's law can't be applied. The light bulb filament violates Ohm’s Law.
Note: Ohm’s law is not applicable for diodes and transistors as they allow the current to flow through in one direction only. For non-straight electrical components with boundaries like capacitance, opposition and so forth the voltage and flow won't be consistent regarding time making it hard to utilize Ohm's law.
