Ohm’s Law is a fundamental principle in physics and electrical engineering. It describes the relationship between electrical voltage, current, and resistance in an electrical circuit. Theory Ohm's Law The law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Such a conductor is characterized by its ‘Resistance’ – R measured in Ohms . V=I×R V is the Voltage in Volts across the conductor. I is the current in Amperes through the conductor. Voltage (V) is directly proportional to current i.e V=I×R. Resistance (R) in inversely proportional to current (I) i.e I = V R Ohm's Law (by the German scientist Georg Simon Ohm) shows the relationship between current through a conductor and the voltage across it. In this article, we’ll cover the Ohm’s Law statement, formula, derivation, experiment circuit, solved examples, applications, and limitations with simple explanations for better clarity. What is Ohm’s Law ? Ohm’s Law , discovered by Georg Simon Ohm in 1827, describes how electricity behaves in conductors. It explains the link between voltage, current, and resistance in a simple mathematical way.
