What is the basic unit of resistance in electrical terms?

The basic unit of resistance in electrical terms is the ohm. Resistance, in the context of Ohm's Law, is defined as the opposition to the flow of electric current in a circuit. The formula that relates voltage (V), current (I), and resistance (R) is expressed as V = I × R, where R is measured in ohms.

When discussing electrical components and systems, understanding resistance is crucial because it directly impacts the current flowing through a conductor when a voltage is applied. The ohm is a fundamental unit derived from the International System of Units (SI), making it essential for grasping basic electrical concepts and calculations.
