What unit is used to measure electrical resistance?

The unit used to measure electrical resistance is the Ohm. This unit is named after the German physicist Georg Simon Ohm, who formulated Ohm's Law, which describes the relationship between voltage, current, and resistance in an electrical circuit. According to Ohm’s Law, resistance (measured in Ohms) is defined as the voltage (in Volts) across a conductor divided by the current (in Amperes) flowing through it.

Understanding resistance in Ohms is fundamental in the field of electrical engineering as it provides insights on how much a material resists the flow of electric current, which is critical for circuit design and analysis. It helps engineers choose components that will operate effectively under specific electrical conditions and ensures the safe operation of electrical systems.
