Question

what do you mean by inductance ?​

Answer 1

Answer:

In electromagnetism and electronics, inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. ... Inductance is defined as the ratio of the induced voltage to the rate of change of current causing it.

What is Induction?

Induction is the magnetic field which is proportional to the rate of change of the magnetic field. This definition of induction holds for a conductor. Induction is also known as inductance. L is used to represent the inductance and Henry is the SI unit of inductance.

1 Henry is defined as the amount of inductance required to produce an emf of 1 volt in a conductor when the current change in the conductor is at the rate of 1 Ampere per second.

Factors Affecting Inductance

Following are the factors that affect the inductance:

• The number of turns of the wire used in the inductor.
• The material used in the core.
• The shape of the core.

Electromagnetic Induction law was given by Faraday which states that by varying the magnetic flux electromotive force is induced in the circuit. From Faraday’s law of electromagnetic induction, the concept of induction is derived. Inductance can be defined as the electromotive force generated to oppose the change in current at a particular time duration.

Types of Inductance

Two types of inductance are there:

• Self Induction
• Mutual Induction

What is Self Inductance?

Self-inductance is the property of the current-carrying coil that resists or opposes the change of current flowing through it. This occurs mainly due to the self-induced emf produced in the coil itself. In simple terms, we can also say that self-inductance is a phenomenon where there is the induction of a voltage in a current-carrying wire.

Mutual Inductance

Mutual inductance is the opposition to the change of current in one coil due to the presence of a second coil. , if a medium of relative permeability μr is present, the mutual inductance would be M =μr μ0 n1n2π r21 l, where n1 and n2 are the numbers of turns of the two coils per unit length, and r1 is the radius of the inner coil and l is the length of the coil.
