skin effect उदाहरण वाक्य

उदाहरण वाक्य

1. For R _ m the skin effect is negligible and the eddy current braking torque follows the theoretical curve of an induction motor.
2. However, it is used in specialized equipment, such as satellites, and as a thin plating to mitigate skin effect losses at high frequencies.
3. Factors that affect the resistance, and thus loss, of conductors used in transmission and distribution lines include temperature, spiraling, and the skin effect.
4. Hence, conductors of such currents exhibit marked skin effect, causing most of the currents to flow through the outer surface of the conductor.
5. However, for skin effect to the significant, the conductor diameter must be large enough, and / or the frequency must be large enough.
6. Proximity and skin effect significantly complicate the design of efficient transformers and inductors operating at high frequencies, used for example in switched-mode power supplies.
7. In radio frequency tuned circuits used in radio equipment, proximity and skin effect losses in the inductor reduce the Q factor, broadening the bandwidth.
8. The efficiency of a transformer may decrease as the frequency increases due to eddy currents in the core material and skin effect on the windings.
9. Since the eddy currents are generated by an AC magnetic field, their penetration into the subsurface region of the material is limited by the skin effect.
10. For R _ m > 30 the skin effect dominates and the braking torque decreases much slower with increasing speed than predicted by the induction motor model.
