Electromagnetic Fields emitted by High Voltage Alternating
... ANALYSIS Offshore wind farms can be connected to the grid either using a high voltage alternating current (HVAC) or high voltage direct current (HVDC) transmission scheme depending on the rating of the windfarm and the distance to shore [14-16]. For HVAC transmission, a three-phase system is general ...

Electromagnetic Induction
... In Part I we shall verify some aspects of this law by observing the current induced in a coil of wire as a permanent magnet is moved (or held steady) near the coil. In Part II the current in the coil of wire will again be observed, but the field at the coil will be caused by a current in another coi ...

... By the maximum power transfer theorem if the impedance of the source and antenna is same then maximum power is transferred in the antenna. We need this because we are using the same coil as the transceiver too, and we don’t need any power to be reflected from the antenna. The reactance of a capacito ...
