Free riding (also known as Freeriding or Free-riding) is a term used in stock-trading to describe the practice of buying and selling shares or other securities without actually having the capital to cover the trade. In a cash account, a free riding violation occurs when the investor sells a stock that was purchased with unsettled funds.
The metal in electric wire is called the conductor. Many materials are used to transmit electrical energy, but those most frequently used are copper, copper-covered steel, hâ¦igh strength copper alloys, and aluminum. i was thinking copper. Silver is the best electrical conductor but its cost prevents its use in ordinary wiring. copper is the next best, with aluminium third. For house wiring copper is almost uni â¦ versal. For overhead power lines aluminium is preferred for its lower density which reduces the cost of overhead lines significantly although slightly larger conductors must be used for a given amount of power.
Silver is the most electrically and thermally conductive metal. Other metals with a high level of electrical conductivity are copper and gold. Conductivity is measured by an element's ability to transmit energy. If an element is considered to be electrically conductive, it means that it has the ability to conduct electricity. Thermal conductivity refers to the transfer of heat. Most metals are able to conduct electricity. Although silver is the most electrically conductive element, copper and gold are more commonly used in wiring and electronics. Copper is used because it is less expensive. Gold is used because it does not corrode as easily as other metals.
