Total energy storage of lc resonant circuit

What is resonance in LC circuit?

The total current in the circuit is split between these two components, depending on their characteristics. In an LC circuit, resonance is a special condition that occurs when the energy stored in the inductor and the capacitor is perfectly balanced, causing the circuit to oscillate at a particular frequency.

What do LC circuits oscillate and resonate?

LC circuits, comprising of inductors (L) and capacitors (C), are key components in electrical and electronic systems. These circuits are characterized by their ability to oscillate and resonate, storing and exchanging energy between the inductor’s magnetic field and the capacitor’s electric field.

How is energy stored in an LC circuit?

In an LC circuit, energy is stored in two forms: magnetic energy in the inductor’s magnetic field and electric energy in the capacitor’s electric field. This energy oscillates back and forth between the electric and magnetic fields as the current and voltage oscillate.

What is resonant frequency in a series LC circuit?

The resonant frequency depends on both these values; smaller inductors or capacitors lead to a higher resonant frequency, while larger values lead to a lower one. At resonance, something important happens: the impedance, which is the total opposition to current flow in the circuit, is at its lowest point in a series LC circuit.

What is the resonant frequency?

The resonant frequency (f_r) is the specific frequency at which the reactive components of an LC circuit cancel each other out, resulting in a purely resistive impedance (in a series LC circuit) or a purely conductive admittance (in a parallel LC circuit). It is determined by the values of the inductor and capacitor.

How LC resonant circuit is used to generate a magnetic field?

To generate a magnetic field, it is necessary to pass an AC current through a coil. An LC resonant circuit is used to apply an AC current to a coil. There are two resonance methods: voltage resonance (parallel LC circuit) and current resonance (series LC circuit). Voltage resonance
