In which unit is resistance measured?

Resistance is measured in ohms, a unit derived from the name of the German physicist Georg Simon Ohm, who is known for formulating Ohm's Law. This law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor.

Ohm's Law is commonly expressed with the formula ( V = I \times R ), where ( V ) represents voltage (measured in volts), ( I ) represents current (measured in amperes), and ( R ) represents resistance (measured in ohms).

The electronic relationship defined by ohms is essential in various electrical applications, such as circuit analysis, designing electronic components, and understanding how electricity behaves in a circuit.

This makes ohms the correct unit for measuring resistance, distinguishing it from the other options, which measure different electrical quantities: volts measure electrical potential, watts measure electrical power, and amperes measure electrical current.
