Standing wave hysteresis loss
Webb5 nov. 2024 · 14.7: Standing waves. As we saw in the last section, when waves have the same frequency, it is possible for them to interfere completely, either destructively or constructively. Waves of the same frequency that interfere can be generated by propagating waves along a string, as the reflected waves from the end of the string will … WebbDue to dispersion, hysteresis losses differ as a function of frequency, which should be considered when selecting a transformer. Can You Reduce Hysteresis Loss? The simple …
