What is the main purpose of an inductor?
Inductor: They are used to block AC while allowing DC to pass; inductors designed for this purpose are called chokes. They are also used in electronic filters to separate signals of different frequencies, and in combination with capacitors to make tuned circuits, used to tune radio and TV receivers.

An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a magnetic field in the clockwise direction.
An Inductor is a passive device that stores energy in its Magnetic Field and returns energy to the circuit whenever required. An Inductor is formed by a cylindrical Core with many Turns of conducting wire.
Do inductors store charge?
As an inductor stores more energy, its current level increases, while its voltage drop decreases. Whereas capacitors store their energy charge by maintaining a static voltage, inductors maintain their energy “charge” by maintaining a steady current through the coil.
So a capacitor allows no current to flow "through" it for DC voltage (i.e. it blocks DC). The voltage across the plates of a capacitor must also change in a continuous manner, so capacitors have the effect of "holding up" a voltage once they are charged to it, until that voltage can be discharged through a resistance.
What is the difference between inductor and capacitor?
These components are passive element's, which draw power from the store, circuit, and then discharge. The main difference between a capacitor and inductor is that an inductor is used to store the energy in the form of magnetic field, whereas a capacitor stores the energy in the form of an electric field.
Why capacitors are used?
Power conditioning. Reservoir capacitors are used in power supplies where they smooth the output of a full or half wave rectifier. They can also be used in charge pump circuits as the energy storage element in the generation of higher voltages than the input voltage.
What are the unit of inductor?
The henry (symbolized H) is the Standard International ( SI ) unit of inductance . Reduced to base SI units, one henry is the equivalent of one kilogram meter squared per second squared per ampere squared (kg m 2 s -2 A -2 ).
What is the function of a diode?
The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking current in the opposite direction (the reverse direction). Thus, the diode can be viewed as an electronic version of a check valve.
Transformers (sometimes called "voltage transformers") are devices used in electrical circuits to change the voltage of electricity flowing in the circuit. Transformers can be used either to increase the voltage (called "stepping up") or decrease the voltage ("step down").
What is the inductance of an inductor?
The property of the coil of inducing EMF due to the changing flux linked with it is known as inductance of the coil. Due to this property all electrical coil can be referred as inductor. In other way, an inductor can be defined as an energy storage device which stores energy in form of magnetic field.
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
It can amplify and switch electrical power and electronic signals. Transistors are made of semiconductor material with three or more terminals used to connect to an external circuit. By applying a current or a voltage to one of the pairs of the terminals, there is a change in current through another pair of terminals.
What are the functions of a transformer?
Explaining Different Types of Transformers. A transformer is an electrical device which, by the principles of electromagnetic induction, transfers electrical energy from one electric circuit to another, without changing the frequency. The energy transfer usually takes place with a change of voltage and current.
What is the reactance?
In electrical and electronic systems, reactance is the opposition of a circuit element to a change in current or voltage, due to that element's inductance or capacitance.
What is the basic function of a capacitor?
Its function is to store the electrical energy and give this energy again to the circuit when necessary. In other words, it charges and discharges the electric charge stored in it. Besides this, the functions of a capacitor are as follows: It blocks the flow of DC and permits the flow of AC.
The main function of resistors in a circuit is to control the flow of current to other components. Take an LED (light) for example. If too much current flows through an LED it is destroyed. So a resistor is used to limit the current.
What is inductance in electrical engineering?
According to Lenz's law, a changing electric current through a circuit that contains inductance induces a proportional voltage, which opposes the change in current (self-inductance). The varying field in this circuit may also induce an e.m.f. in neighbouring circuits (mutual inductance).
