In electrical terminology, what is measured in ohms?

Resistance is measured in ohms, which is a fundamental unit in the field of electricity and electronics. The concept of resistance reflects how much a material opposes the flow of electric current. According to Ohm's Law, the relationship between voltage (measured in volts), current (measured in amperes), and resistance can be expressed as V = I × R, where V is voltage, I is current, and R is resistance. This law helps to establish a clear understanding of how these three elements interact within an electrical circuit.

Resistance is an important factor in determining how much current will flow for a given voltage; higher resistance means less current flow, while lower resistance allows more current to pass through. Understanding resistance and its measurement in ohms is crucial for designing and troubleshooting electrical circuits, ensuring that they operate safely and efficiently.
