What is the measurement unit for electrical resistance?

The measurement unit for electrical resistance is the Ohm. This unit quantifies how much a material opposes the flow of electric current. According to Ohm's Law, resistance (measured in Ohms) is equal to the voltage (measured in Volts) divided by the current (measured in Amperes). This relationship highlights the role of resistance in determining how much current will flow for a given voltage.

Understanding this principle is crucial for analyzing electrical circuits, as resistance affects how components behave within the system. Additionally, the Ohm is part of the International System of Units (SI), which standardizes measurements across various fields of science and engineering, underscoring its fundamental importance in electrical applications.
