What is the basic principle of Ohm's Law?

The basic principle of Ohm's Law is that voltage across a conductor is directly proportional to the current flowing through it if the temperature remains constant. This relationship is expressed mathematically as voltage equals current times resistance (V = I × R). In this context, voltage (V) is the potential difference, current (I) is the flow of electric charge, and resistance (R) is the opposition to the current.

In practical terms, Ohm's Law helps in analyzing electrical circuits by allowing you to calculate any one of these three quantities if you have the other two. Understanding this law is fundamental in electrical engineering and applications, as it governs how electrical components behave under different conditions.

This principle lays the groundwork for many more complex theories and applications in electronics and electrical engineering, making it a cornerstone of electrical concepts.
