Ohm's Law is a cornerstone concept in the study of electrical circuits. It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. Mathematically, it is expressed as:
Here, is the potential difference (voltage) in volts, is the current in amperes, and is the resistance in ohms.
This fundamental principle helps us understand how electrical circuits operate, making it a crucial element in the analysis of electrical systems.
In the context of our exercise, Ohm's Law was used to determine the voltage necessary to create a specific current flow through the human body, represented as a cylindrical conductor. This shows how even a small voltage can result in a dangerous current if the resistance is sufficiently low.
