Ohmic resistance is the property of a material that quantifies how much it opposes the flow of electric current, following Ohm's Law. It is characterized by a linear relationship between voltage and current, where the resistance remains constant regardless of the current passing through the material.

Electric current is the flow of electric charge through a conductor, typically measured in amperes. It is a fundamental aspect of electricity, enabling the operation of electrical devices and the transmission of power across distances.

Ohm's Law is a fundamental principle in electronics and electrical engineering that states the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. This relationship is mathematically expressed as V = IR, where V is voltage, I is current, and R is resistance.

Ohm's Law

A linear relationship describes a direct proportionality between two variables, where a change in one variable results in a consistent change in the other. This relationship is graphically represented by a straight line on a Cartesian plane, characterized by its slope and intercept.

Resistance is the opposition that a substance offers to the flow of electric current, measured in ohms. It is a fundamental concept in physics and engineering, affecting how electrical circuits function and influencing the design of electronic components.
