Transformer Emf Equation Ppt . The constant “k” is known as voltage transformation ratio. Circuits are separated, as depicted in figure 2, the steady state loop equations are simply: PPT Transformers PowerPoint Presentation, free download from www.slideserve.com Delivery of a good speech along with the given slides would make the greatest of combination. Construction, types of transformers, emf equation, concept of leakage flux and leakage reactance, operation of transformer under no load and on load, phasor diagrams, equivalent circuit, efficiency, regulation and all day efficiency; The main principle of the emf equation of transformer is presented below.
In Resistance Welding The Voltage Supplied Is. Are worked on the same principle of heat generation due to electric resistance. (d) all of the above.

Thus, this is all about the resistance welding process, which is used for welding two metals. (d) either (a) or (b) and (c). Transformers are usually thought of as stepping voltage up or down, but current can also be transformed in the same way.
| In Resistance Welding The Voltage Supplied Is:
The voltage needed in resistance welding does not depend upon a. Resistance welding is a pressure welding process in which it joins the two workpieces together by raising the temperature to the fusion point and applying mechanical pressure to join between them. In constant temperature resistance welding, sensors, such as thermocouples, are used to monitor the welding process to adjust current and voltage as necessary.
In Words Voltage Is Equal To Current Multiplied By Resistance.
In a little more detail, the welding power supply transforms, modulates and controls the electrical energy of the power line and applies it to the weld according to a user defined or user programmed “weld schedule.” The voltage required ranges from 4 to 12 v; Therefore, to get the 10,000 amps needed for resistance welding, some device must be used to step the current up from the relatively low level available from the power line.
(D) Either (A) Or (B) And (C).
In general, the highest resistance results in the highest heat assuming that the resistance welding power supply can produce sufficient energy to overcome the resistance. The temperature reached is not very high as in case of arc welding. When the force is applied, the resistance produces heat, then resistance welding utilizes the heat.
(C) The Electrodes Used Are Of Disc Or Roller Shape.
(a) the workpiece is fixed and disc electrodes move. Resistance welding is to focus the heat generated close to the weld interface at the spot where the weld is desired. (d) either (a) or (b) and (c).
The Voltage Used In Resistance Welding Is Generally Kept Between A.
Modes of metal transfer in arc welding • the depth of penetration, the stability of the. Resistance welding machines invariably have at least one electrode which moves with considerable force; The kva required for resistance welding, when actually making a weld, ranges from a.
