Comparison Between Inductor and Capacitor
What is Inductor?
An inductor is an electrical component that stores energy in the form of a magnetic field. It is typically a coil of wire wound around a core made of a magnetic material. When a current flows through the coil, a magnetic field is generated, and this magnetic field stores energy.
The basic principle behind an inductor is Faraday's law of electromagnetic induction
Inductor
👉An inductor is a passive component that stores energy in a magnetic field when current flows through it. It opposes changes in current and allows DC to pass through while impeding AC signals.
👉The symbol for an inductor is a coil or a series of loops
👉Inductors have higher impedance (reactance) to high-frequency signals and lower impedance to low-frequency signals
👉Inductors resist changes in current and do not allow direct current (DC) to pass through easily.
👉An inductor is typically made of a coil of wire wound around a core made of magnetic material, such as iron or ferrite.
👉inductors are characterized by their inductance, which is a measure of their ability to store energy in a magnetic field. Inductance is measured in units called henries (H).
👉Inductors exhibit reactance, which is their opposition to the change in current with respect to the frequency of the applied signal. The reactance of an inductor increases with increasing frequency.
👉Inductors are used in filter circuits to block certain frequencies and allow only desired frequencies to pass.
Inductors store energy in applications such as transformers and magnetic ballasts.
👉Inductive loads, such as motors and solenoids, use inductors to convert electrical energy into mechanical energy.
👉Inductors are used in oscillator circuits to generate continuous oscillations.
👉Inductors tend to resist changes in current, making them suitable for applications involving time delays or filtering low-frequency signals.
👉Inductors have energy dissipation due to resistive losses in the coil winding.
👉Inductors store energy in the form of current. The higher the current flowing through an inductor, the higher the energy stored.
👉Inductors are commonly used in applications such as filtering, energy storage, transformers, and inductive loads.
👉The time constant of an inductor depends on the inductance value and the resistance in the circuit.
👉Inductors add in series and reduce in parallel.
👉Inductors do not have voltage polarity, meaning they do not have a specific positive or negative terminal.
👉The impedance of an inductor increases with frequency (inductive reactance = 2πfL) and decreases with resistance.
👉Inductors cause phase delays in current with respect to voltage in AC circuits.
👉When power is removed from an inductor, it releases the stored energy back into the circuit.
👉Inductors resist changes in current and exhibit slower transient responses.
👉Inductors pass low-frequency signals and attenuate high-frequency signals.
👉The impedance of an inductor increases with frequency, making it more effective at higher frequencies.
👉The energy storage in an inductor is primarily associated with the magnetic field.

what is Capacitor?
A capacitor is an electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material called a dielectric. When a voltage difference is applied across the plates, an electric field is formed between them, and the capacitor stores energy in this field.
