It ends huh , not really sure how to feel about an ending like this . <| sep |> My suggestion is creating a loadout on loadout . tf , check the wiki if all of the cosmetics that you used are singleclass , then check backpack . tf if they ' re affordable . <| sep |> We already have it in Newcastle . Choice is pretty limited though , so not used it since the novelty wore off . <| sep |> Does that work again ? Site was down the last couple times I ' ve tried . <| sep |> Damn . Been wanting a good wireless headset to replace my g 930 . Just not sure if I really need to drop $ 99 on anything right now . <| sep |> Plost , often short for Power Lost in mathematics is a common occurrence in conductors which is often compounded by the arrangement of the conductor . For example , an inductor coil consists of a number of twists of wire , and since all wire has some resistance , every inductor has a certain amount of resistance . Normally this resistance is small . It is usually neglected in solving various types of ac circuit problems because the reactance of the inductor the opposition to alternating current , which will be discussed later is so much greater than the resistance that the resistance has a negligible effect on the current . However , since some inductors are designed to carry relatively large amounts of current , considerable power can be dissipated in the inductor even though the amount of resistance in the inductor is small . This power is wasted power and is called COPPER LOSS . The copper loss of an inductor can be calculated by multiplying the square of the current in the inductor by the resistance of the winding I 2 R . In addition to copper loss , an ironcore coil inductor has two iron losses . These are called HYSTERESIS LOSS and EDDYCURRENT LOSS . Hysteresis loss is due to power that is consumed in reversing the magnetic field of the inductor core each time the direction of current in the inductor changes . Eddycurrent loss is due to heating of the core by circulating currents that are induced in the iron core by the magnetic field around the turns of the coil . These currents are called eddy currents and circulate within the iron core only . All these losses dissipate power in the form of heat . Since this power cannot be returned to the electrical circuit , it is lost power . Whenever two coils are located so that the flux from one coil links with the turns of the other coil , a change of flux in one coil causes an emf to be induced in the other coil . This allows the energy from one coil to be transferred or coupled to the other coil . The two coils are said to be coupled or linked by the property of MUTUAL INDUCTANCE M . The amount of mutual inductance depends on the relative positions of the two coils . This is shown in figure 212 . If the coils are separated a considerable distance , the amount of flux common to both coils is small and the mutual inductance is low . Conversely , if the coils are close together so that nearly all the flux of one coil links the turns of the other , the mutual inductance is high . The mutual inductance can be increased greatly by mounting the coils on a common iron core . Two coils are placed close together . Coil 1 is connected to a battery through switch S , and coil 2 is connected to an ammeter A . When switch S is closed , the current that flows in coil 1 sets up a magnetic field that links with coil 2 , causing an induced voltage in coil 2 and a momentary deflection of the ammeter . When the current in coil 1 reaches a steady value , the ammeter returns to zero . If switch S is now opened the ammeter A deflects momentarily in the opposite direction , indicating a momentary flow of current in the opposite direction in coil 2 . This current in coil 2 is produced by the collapsing magnetic field of coil 1 . The mutual inductance of two adjacent coils is dependent upon the physical dimensions of the two coils , the number of turns in each coil , the distance between the two coils , the relative positions of the axes of the two coils , and the permeability of the cores . The COEFFICIENT OF COUPLING between two coils is equal to the ratio of the flux cutting one coil to the flux originated in the other coil . If the two coils are so positioned with respect to each other so that all of the flux of one coil cuts all of the turns of the other , the coils are said to have a unity coefficient of coupling . It is never exactly equal to unity 1 , but it approaches this value in certain types of coupling devices . If all of the flux produced by one coil cuts only half the turns of the other coil , the coefficient of coupling is 0 . 5 . The coefficient of coupling is designated by the letter K . The mutual inductance between two coils , L 1 and L 2 , is expressed in terms of the inductance of each coil and the coefficient of coupling K .
