Q1: An air gap provided in the iron core of an inductor preventsA flux leakage
B hysteresis loss
C core saturation
D heat generation
ANS:C - core saturation When AC signals are applied, this nonlinearity can cause the generation of harmonics and intermodulation distortion. To prevent this, the level of signals applied to iron core inductors must be limited so they don't saturate. To lower its effects, an air gap is created in some kinds of transformer cores. |
