When should you use an inductor?
Inductors are used as the energy storage device in many switched-mode power supplies to produce DC current. The inductor supplies energy to the circuit to keep current flowing during the "off" switching periods and enables topographies where the output voltage is higher than the input voltage.
Why are capacitors and inductors used?
Capacitors act as an insulator for DC circuits. They are ideal for conducting high-frequency signals. Inductors act as a conductor for DC circuits. They are good at conducting low-level frequencies, and filter out high-frequency signals and oscillations.
How does inductor store energy?
Inductors Store Energy. The magnetic field that surrounds an inductor stores energy as current flows through the field. ... An alternating current (AC) flowing through the inductor results in the constant storing and delivering of energy.
What is main function of inductor?
An inductor has the functions of developing electromotive force in the direction that reduces fluctuation when a fluctuating current flows and storing electric energy as magnetic energy.
What is the point of an inductor?
Inductors are primarily used in electrical power and electronic devices for these major purposes: Choking, blocking, attenuating, or filtering/smoothing high frequency noise in electrical circuits. Storing and transferring energy in power converters (dc-dc or ac-dc)
How is an inductor used in an electrical circuit?
An inductor is defined as a passive component that is used in most electrical circuits to store energy in the form of magnetic energy when electric current flows through it. It is also known as the coil, choke, or reactor. It is a two-terminal electrical component that is characterized by its inductance.
Can a capacitor be used as an inductor?
In general, the behavior of an inductor is the dual to that of a capacitor, so most functions that require one can be implemented by using the other, but in a different arrangement. But that's not always true. For example, if you only want to receive low-frequency energy, you can put in a resistor, followed by a capacitor to ground.
What happens to the current when the inductor is turned off?
The current won’t just stop flowing in the inductor in an instant. So when you switch off the power, the inductor will try to continue the current flow. It does this by quickly increasing the voltage across its terminals. It actually increases so much that you can get a little spark across the pins of your switch!
Why do you use an inductor in a tweeter?
The reason to use an inductor there is that it doesn't "consume" or "waste" the high frequency energy, it just blocks it from passing, so that energy can then pass through the capacitor, to the tweeter, instead.
