Ohm’s Law Definition

380 words | 2 page(s)

Ohm’s law was developed in 1827 stating that “the current flowing through a conductor is directly proportional to the potential difference across its ends” (Sardar 90). In other words, the current that flows through a conductor at constant temperature is directly proportional to the potential difference across the ends of that conductor. The Ohm’s law formula is V = R x I, where V is the potential difference, I stands for current, and R means constant resistance. Ohm’s law is a necessary tool for analyzing the electronic circuit. It is applicable for studying hydraulic analogy, heat conductivity, electrical circuits, linear approximations, etc. such applicability defines the ways Ohm’s law is used in everyday life.

Electrical circuits are present within the systems of flight and engine control, in cockpit instrumentation, and in the winds tunnel operation and instrumentation (“Ohm’s Law”). All of the abovementioned systems use resistors which function under the Ohm’s law. Not only the aerospace industry finds the Ohm’s law to be useful, but it applies to every electronic device in the healthcare settings (Tenny, and Dulebohn 5). It is unnecessary for the clinicians to calculate current, voltage, and resistance for the operated medical devices because most of those devices are operated based on the intuition. Furthermore, Ohm’s law is present in the human body, for example, the messages between the nerves in the central nervous system are sent using the electrical properties. Those signals can be traced using sensors to give better comprehension of the nerves’ activity to the doctors.

Overall, the Ohm’s law is a representation of the relationship between the voltage, current, and resistance. It is widely applicable to the creation and analysis of the electronic circuits, development of the batteries, and in other various electrochemical ways of use. The Ohm’s law should be considered when using electricity to receive the intended output.
