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.
IV Rank. IV rank measures where current implied volatility stands in relation to the range it has been in for a given period of time. The max rank is 100 and the minimum rank is 0. For example, suppose the past four IV readings were 20, 22, 35 and 40.
