Ohms is the correct unit of measurement for resistance in Ohm's Law. In electrical circuits, Ohm's Law states the relationship between voltage (measured in volts), current (measured in amps), and resistance (measured in ohms). The formula can be expressed as V = IR, where V is voltage, I is current, and R is resistance.

Resistance is a measure of the opposition that a circuit presents to the flow of electric current. Understanding resistance in ohms is crucial for electrical engineers and technicians as it helps in designing and analyzing circuits and ensuring that they operate safely and efficiently. The use of ohms as a unit of measurement for resistance directly relates to the work of George Simon Ohm, after whom the unit is named.
