What unit is used to measure electrical resistance?

The unit used to measure electrical resistance is Ohms. This measurement is a fundamental aspect of electrical engineering and is derived from Ohm’s Law, which states that voltage (measured in Volts) is equal to the product of current (measured in Amperes) and resistance (measured in Ohms). The concept of resistance is crucial in understanding how electrical circuits operate, as it quantifies how much a material opposes the flow of electric current.

In a circuit, the higher the resistance in Ohms, the less current will flow for a given voltage. This relationship helps engineers design circuits effectively to manage power and current flow. Understanding and measuring resistance in Ohms is essential for troubleshooting electrical issues and for the safe and efficient design of electrical systems.
