What Is Inductance And Its Uses?

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.



Where are resistors used in everyday life?

Because of the nature of generating heat when conducting current, resistors are used in a heater, toaster, microwave, electric stove, and many more heating appliances. In a light bulb, the metal filament glows white-hot due to the very high temperature produced from the resistance when electricity is passed through it.


What is mutual inductance in physics?

Mutual Inductance is the basic operating principal of the transformer, motors, generators and any other electrical component that interacts with another magnetic field. Then we can define mutual induction as the current flowing in one coil that induces a voltage in an adjacent coil.


How do you find mutual inductance?

Using the previous expression and the given values, the mutual inductance is M=(4π×10−7T⋅m/A)(500)(10)π(0.0310m)20.750m=2.53×10−5H. Thus, from Equation 14.2. 6, the emf induced in the surrounding coil is ϵ2=−MdI1dt=−(2.53×10−5H)(200A/s)=−5.06×10−3V.


What is mutual inductance in network analysis?

Mutual inductance occurs when two circuits are arranged so that the change in current in one causes a voltage drop to be induced in the other.


What are examples of mutual inductance?

The heating coils of an electric clothes dryer can be counter-wound so that their magnetic fields cancel one another, greatly reducing the mutual inductance with the case of the dryer. Digital signal processing is another example in which mutual inductance is reduced by counter-winding coils.


How is mutual inductance formula derived?

Mutual Inductance Derivation

  1. However, it depends upon the following factors:
  2. We know that an EMF is induced in the secondary coil.
  3. e2 = - d(ф2)T/dt = - d(MI1)/dt.
  4. (Its because the flux of S coil, i.e., (ф2)T depends on the current (I1) in the P coil)
  5. e2 = - M dI1/dt.
  6. If dI1/dt = 1, then M = - e2


What are the applications of resistors?

  • Resistors are used in filter circuit networks.
  • It is used in amplifiers, oscillators, telecommunication and digital multimeter.
  • It is used in wave generators.


What is mutual induction quizlet?

mutual induction. the induction of electricity in a secondary coil by a moving magnetic field. a moving magnetic field that is placed near a secondary coil. electricity is induced to flow in that coil.


Do computers use inductors?

Large inductors are used in the power supplies of electronic equipment of all types, including computers and their peripherals. In these systems, the inductors help to smooth out the rectified utility AC, providing pure, battery-like DC.


What appliances use inductors?

Applications of Inductor

  • Inductors in Tuned Circuits.
  • Inductive sensors. Energy Storage Devices.
  • Induction Motors.
  • Transformers.
  • Inductive Filters.
  • Chokes.
  • Ferrite beds.
  • Relays.


Where are inductance used?

Inductors are typically used as energy storage devices in switched-mode power devices to produce DC current. The inductor, which stores energy, supplies energy to the circuit to maintain current flow during “off” switching periods, thus enabling topographies where output voltage exceeds input voltage.


What is mutual inductance and where does it come from?

When two coils are brought in proximity with each other the magnetic field in one of the coils tend to link with the other. This further leads to the generation of voltage in the second coil. This property of a coil which affects or changes the current and voltage in a secondary coil is called mutual inductance.


Which rule is used to find the direction of the induced emf in a coil?

right hand rule


What is inductance and its uses?

Who discovered mutual induction?

Joseph Henry (1797-1878) discovered the phenomenon of mutual inductance independently and more or less simultaneously with Michael Faraday.


What is mutual inductance transformer?

Mutual inductance is where the magnetic flux of two or more inductors are “linked” so that voltage is induced in one coil proportional to the rate-of-change of current in another. A transformer is a device made of two or more inductors, one of which is powered by AC, inducing an AC voltage across the second inductor.


Do transformer works on mutual induction?

A transformer works on the principles of "electromagnetic induction" as a mutual induction. Mutual induction is the process by which a coil of wire magnetically induces a voltage in another closely located coil.


Which device works on the principle of mutual induction?

transformer
