Ohm’s Law Explained
Ohm’s Law is a fundamental principle in electrical engineering that relates the voltage, current, and resistance in an electrical circuit. It’s named after the German physicist Georg Simon Ohm, who first formulated it in the 19th century. Ohm’s Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.
Mathematically, Ohm’s Law can be expressed as:
V = I x R
Where:
– V represents the voltage across the component in volts (V).
– I represents the current flowing through the component in amperes (A).
– R represents the resistance of the component in ohms (Ω).
This formula can also be rearranged to find the current or resistance:
I = V/R
R = V/I
Ohm’s Law is incredibly useful in understanding and analyzing electrical circuits. It allows engineers and technicians to predict how changes in voltage, current, or resistance will affect the behavior of a circuit. Whether designing circuits, troubleshooting problems, or calculating power dissipation, Ohm’s Law serves as a foundational principle guiding the study and application of electronics.
