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).
rated frequencyrated impedancerated outputrated powerrated resistance. rated current. 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.
