when in LC oscillation current flow from inductance to capacitor and charge is opposite polarity. why don't current flow in reverse of it and charging the capacitor in same manner as it was earlier.

I don’t understand what you are saying. Can you add a picture or an equation explaining what you want to know?

What searching online have you done so far to find an answer ?

## 1. What is LC oscillation?

LC oscillation is a type of electrical oscillation that occurs in circuits containing inductors (L) and capacitors (C). It is an alternating current (AC) circuit where energy is continuously exchanged between the inductor and capacitor. This results in a periodic oscillation of the current and voltage in the circuit.

## 2. How does current flow in an LC oscillating circuit?

In an LC oscillating circuit, current flows back and forth between the inductor and capacitor. When the capacitor is fully charged, the current flows through the inductor and creates a magnetic field. As the capacitor discharges, the current flows through the capacitor and creates an electric field. This continuous exchange of energy between the inductor and capacitor results in oscillation.

## 3. What is the polarity of charge in an LC oscillating circuit?

The polarity of charge in an LC oscillating circuit alternates between positive and negative as the capacitor charges and discharges. When the capacitor is fully charged, the top plate has a positive charge and the bottom plate has a negative charge. As the capacitor discharges, this polarity is reversed.

## 4. What factors affect the frequency of an LC oscillation?

The frequency of an LC oscillation is affected by the values of the inductor and capacitor in the circuit. The higher the values of these components, the lower the frequency. Additionally, the resistance of the circuit and any external factors such as temperature can also affect the frequency.

## 5. How is an LC oscillation different from other types of oscillations?

Unlike other types of oscillations, such as mechanical or acoustic oscillations, an LC oscillation relies on the exchange of energy between the inductor and capacitor. It is also a type of electrical oscillation, meaning it occurs in circuits containing electronic components, rather than physical objects like a pendulum or sound waves.
