Electrical resistivity is a property of materials and is different from electrical resistance which is a property of a component. Resistivity is also known as Specific Electrical Resistance or Volume Resistivity. Resistivity can also be defined as the inverse of the conductivity of a material - Ï = 1 / Ï.It is a measure of how a material opposes the flow of electric current. The SI unit of resistivity is ohm meter (Ï.m).

A rated or named value, stating the current that a component, circuit, device, piece of equipment, system consumes, produces, or safely tolerates, when used in a given manner. For example, it may be a rating of the current drawn expressed in RMS amperes after a device is turned on and warmed up. The actual value, or interval of values, may not coincide with this number. Also called nominal current.
In simpler terms. Full load current: Is the maximum current that a electrical machine can draw/supply safely by meeting(either supplying or consuming) the full-load conditions. Rated Current: The current rated on the nameplate of a electrical machine (this is in-fact full load current). The equipment should be operated in such a way that this current shall not exceed at any given time.
