At the core of electrical engineering and physics lies the fundamental principle known as Ohm's Law. This principle elucidates a vital connection between three key elements in an electrical circuit : voltage (V), current (I), and resistance (R). Mathematically expressed as:
V = I × R
Ohm's Law serves as a guiding equation, providing insights into the intricate relationship among these essential parameters. In essence, to grasp the resistance (R) within a circuit, one must simultaneously comprehend the voltage across its terminals (V) and the intensity of the current (I) flowing through it. This foundational concept forms the bedrock of electrical understanding and measurement, shaping the way we analyze and engineer electrical systems.
