Capacitor vs. Inductor
Energy is believed to be stored in a capacitor in the form of an electric field. On the other hand, we store energy in an inductor in the form of a magnetic field.
The capacitor is known as the electrical component that comprises two conducting plates. An inductor, on the flip side, is simply considered as a wire that contains two terminals and is always nearly coiled.
A capacitor is the best device for the conduction of signals that have high-frequency. Inductor, on the other side, is referred to as the devices that show the best conduction at low-level frequencies.
We can also use a conductor for blocking out the signals that contain low-frequency or noise. On the other hand, high-frequency signals and oscillations are filtered out through the insulator.
What is a Capacitor?
The capacitor is known as an electrical component. It is mainly composed of two conductors that are alienated by an insulator. An electric field is formed when we apply a potential difference to both the terminals, and thus we store the electric charges. We mainly find the applications of capacitors in the formation of electronic circuits.
We can use any non-conducting substance as a die electric substance. But, Mylar, porcelain, Teflon, cellulose, and mica are considered as some dielectric materials that are preferred by us. We define the capacitors on the basis of the materials that we choose, like dielectric or electrode.
In order to store electrical energy, we mainly use dielectric materials. In order to determine the value of the capacitor, we consider the kind of material used, the size of the terminals, and the distance between the two terminals.
We connect the capacitors in parallel unite as the resistors are connected in series, while we connect the capacitors in series unite as the resistors are connected in parallel. We mainly classify the capacitors into three types that are the tantalum, ceramic, and electrolytic.
Uses
- In power supplies, we use the high Voltage Electrolytic capacitors.
- An Axial Electrolytic capacitor is used by us for general purposes in a lower voltage of a smaller size where we need the principles of huge capacitance.
- High Voltage disk ceramic capacitor is referred to as a small size capacitor that comprises the excellent tolerance characteristics and the value of capacitance.
- For good reliability, we use the Metalised Polypropylene capacitor that is considered as a small size capacitor and has the values up to 2µF.
What is Inductor?
An inductor is also named as a coil or a choke and is referred to as a two-terminal device that is used by mankind to build various circuits. The storage of energy in a magnetic field is considered as the main function of an inductor. It is mainly composed of a wire that is generally twisted into a coil.
The current is temporarily stored in the coil when current flows through it. For direct current, an absolute inductor is believed to be equivalent to a short circuit, and hence an opposing force is granted to the flow of alternating current that is based on the frequency of the current.
The opposition that is offered to the flow of the current of an inductor has an association with the frequency that is comprised by the flowing current. We arrange the inductors in parallel unite as the resistors are arranged in parallel, and they are arranged in series unites as a resistor is arranged in series.
We mainly classify the inductors into three main types that include the Coupled inductors, Multilayer Inductors, Molded Inductors, and Ceramic Core Inductors.
Uses
- We extensively use the inductors in the applications of alternating current (AC) like TV, radio, etc.
- The main property of an inductor is chokes that we use in power supply circuits in which the AC mains supply is desired to be changed to a DC supply.
- In automobile engines, we use the inductors that are responsible for making the spark that, in turn, catch fires the petrol.
- In order to form a transformer, we unite the inductors that comprise a distributing magnetic lane.
ConclusionAll of the above discussion concludes that capacitor is referred to as an electrical component that is involved in the opposition of the abrupt changes that occur in voltage (dV/dt), on the flip side, an inductor is referred to as an electrical component that is involved in the opposition of the abrupt changes that occur in current (dI/dt).
