Ohms are the units of electrical resistance. They are named after the German physicist Georg Ohm, who discovered the relationship between current, voltage, and resistance in 1827. Resistance is a measure of how difficult it is for current to flow through a material. The higher the resistance, the more difficult it is for current to flow.
Ohms are important because they allow us to calculate the amount of current that will flow through a circuit. This information is essential for designing and building electrical circuits.
