What is the difference between free and forced electromagnetic oscillations?

Free vibrations are the vibrations that occur in an electrical circuit after it is taken out of equilibrium (for example, a capacitor is charged). Forced oscillations occur under the action of a periodically changing electromotive force.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
