Ohm's Law | Basic Electronics | Mobile Phone Repair

Ohm's Law is a fundamental principle in basic electronics that establishes a relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. It is named after the German physicist Georg Simon Ohm, who first formulated the law in the 1820s.
Mathematically, Ohm's Law is represented by the equation:
V=I⋅R
where:
~V is the voltage across the circuit (measured in volts),
~I is the current flowing through the circuit (measured in amperes),
~R is the resistance in the circuit (measured in ohms).
This law asserts that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, given a constant temperature (Ohm's Law is applicable to resistive materials under constant temperature conditions). In practical terms, it provides a foundation for understanding and calculating the behavior of electric circuits, helping engineers and hobbyists design and analyze electrical systems.
