soon becomes a must have in every Manhattan business and soon half of Manhattan is connected when the world’s first power station is built but a treat soon emerges George Westinghouse and his employee Nicholas tesla who are using alternating current. Alternating current wins the battle but tesla makes a careless mistake by ripping up the patent. Morgan threatens Westinghouse with patent infringement. Westinghouse has no choice but to sell his company to Morgan the company soon becomes one of the

footwear are NOT allowed to enter the laboratory) 1 FE1073-E2 MAGNETIC FIELD 1. OBJECTIVES When current exists in an infinitely long straight wire‚ a B field will exist in the region surrounding the wire. If the current is constant in time‚ the B field that exists will be constant in time at a given point. This presence of the constant B field can be detected by a small compass. If the current in the wire is time-varying‚ the B field that exists will also be time-varying. This time-varying

coupling between its winding circuits. A varying current in the primary winding creates a varying magnetic flux in the transformer’s core and thus a varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (EMF)‚ or "voltage"‚ in the secondary winding In electrical engineering‚ two conductors are referred to as mutual-inductively coupled or magnetically coupled [1] when they are configured such that change in current flow through one wire induces a voltage

George Westinghouse II The Westinghausen family tree stretches back to that of the ninth century in Westphalia‚ Germany. Some of the family decided to emigrate to Europe and later settle in the United States. In the nineteenth century‚ George Westinghouse decided to move all over the former United States and settled in Central Bridge‚ New York where he had George Westinghouse II. Born into a family of ten (which would become twelve later on) on October 16‚ 1846‚ George Westinghouse Jr. (son of
