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.
What is 'Current Price' The current price is the actual selling price of a security trading on an exchange, as well as the most recent price of a security listed in an investment portfolio. In the case of a bond, a bond's current price will often be quoted as 10% of the par value of $1000. A bond that currently trades at $99 is really priced at $990. Current price also refers to the present price of a stock, currency, commodity, stamps or a precious metal. BREAKING DOWN 'Current Price' The current price, also known as the market value, is the price at which goods are currently being sold in the market. Similar to market price, which is the price determined by buyers and sellers in an open market, the current price of a security is the price at which
