Problems forced electromagnetic oscillations
Answers
Answer:
Forced Oscillations: Resonance. Forced oscillations occur when an oscillating system is driven by a periodic force that is external to the oscillating system. ... The physically interesting aspect of a forced oscillator is its response—how much it moves—to the imposed driving force.
These oscillations are known as forced or driven oscillations. ... If it oscillates with its natural frequency, the motion will die out. A good example of forced oscillations is when a child uses his feet to move the swing or when someone else pushes the swing to maintain the oscillations.
The object of this investigation is a study of the current distribution in or on the surface of a conductor and its associated field under the influence of a localized e.m.f. Steady‐state solutions of the field equations are found for conductors of simple geometric form. The results clarify many electromagnetic problems involving localized sources, especially in the u‐h‐f region, for which ordinary circuit theory fails to give a satisfactory quantitative explanation. Part I treats the problem of a straight cylindrical conductor and shows the relation of the principal
