Investigate electrical oscillation by charge and discharge

[licheukfan]

I have several question to ask?
1)why the voltage oscillates and amplitude decrease ?
2)how the frequency be affected by varing capacitance value and removed double c core ?
3)what is the corresponding physical quantities between spring -mass oscillation and electical oscillation?

I have a few ideas:
1)since the capacitor is fully charged,when the switch isset to discharge the capacitor,there is a sudden increase in current in the inductor,B-field is induced ,then the induced current is inversely return to the capacitor,in this process ,energy is dissipated,thus V oscillate,A decrease

2)because f=2 (pi)(1/LC)^1/2
thus L or C increase ,resulted in f decrease

3)m/k=1/LC ?

in spring -mass system,m is mass,k is spring constant,in electrical oscillation system,L is inductance,C is capacitance.

Thank you for your questions. I would suggest conducting further experiments and research to fully understand the behavior of electrical oscillations. However, here are some possible explanations for your questions:

1) The voltage oscillates and the amplitude decreases because of the discharge process. When the capacitor is fully charged, it has a high potential difference between its plates. When the switch is set to discharge, the capacitor releases this energy in the form of a current. As the capacitor discharges, the potential difference decreases, leading to a decrease in voltage. This process repeats, resulting in the oscillation of voltage.

2) The frequency of electrical oscillation is affected by the values of capacitance and inductance. As you mentioned, the frequency is inversely proportional to the square root of the product of capacitance and inductance. Therefore, changing either of these values will affect the frequency. Removing a double c core would change the inductance, thus affecting the frequency.

3) There are some similarities between spring-mass oscillation and electrical oscillation. In both cases, there is an oscillation of energy between two forms. In spring-mass oscillation, the energy is transferred between kinetic and potential energy of the mass. In electrical oscillation, the energy is transferred between the electric field and magnetic field of the inductor and the potential energy of the capacitor. The equation you mentioned, m/k=1/LC, is known as the resonance frequency equation and is used to calculate the frequency of both types of oscillations. However, it is important to note that the physical quantities involved in each type of oscillation are different, so this equation is only applicable in certain cases.

I hope this helps to answer your questions. As mentioned before, further experimentation and research can provide a more thorough understanding of electrical oscillation. Keep asking questions and exploring the topic to deepen your understanding.
