Ohms are the models {of electrical} resistance. They’re named after the German physicist Georg Ohm, who found the connection between present, voltage, and resistance in 1827. Resistance is a measure of how tough it’s for present to movement by way of a fabric. The upper the resistance, the tougher it’s for present to movement.
Ohms are necessary as a result of they permit us to calculate the quantity of present that can movement by way of a circuit. This info is important for designing and constructing electrical circuits.
