Test: Reluctance - Question 1

 Reciprocal of reluctance is __________

Detailed Solution for Test: Reluctance - Question 1

The reciprocal of reactance is permeance. It is the ability of a material to allow the passage of magnetic lines of flux.

Test: Reluctance - Question 2

Reluctance is ________________ to the length of the material.

Detailed Solution for Test: Reluctance - Question 2

The formula for reluctance is:
S= l/∫0 ∫rA.
From the formula, we can see that reluctance is directly proportional to the length of the material.

Test: Reluctance - Question 3

Reluctance is ________________ to the area of cross section the material.

Detailed Solution for Test: Reluctance - Question 3

The formula for reluctance is:
S= l/∫0 ∫rA.
From the formula, we can see that reluctance is inversely proportional to the area of cross section of the material.

Test: Reluctance - Question 4

 When the length of the material increases, what happens to reluctance?

Detailed Solution for Test: Reluctance - Question 4

Reluctance is directly proportional to the length of the material hence as length increases, reluctance also increases.

Test: Reluctance - Question 5

When the area of cross section of the material increases, what happens to reluctance?

Detailed Solution for Test: Reluctance - Question 5

Reluctance is inversely proportional to the area of cross section of the material hence as area increases, reluctance decreases.

Test: Reluctance - Question 6

Unit of reluctance is?

Detailed Solution for Test: Reluctance - Question 6

Reluctance is the force per unit flux, hence its unit is A/Wb.

Test: Reluctance - Question 7

 The electrical equivalent of reluctance is?

Detailed Solution for Test: Reluctance - Question 7

Resistance is the opposition to the flow of charge, similarly reluctance is the opposition to the flow of magnetic flux.

Test: Reluctance - Question 8

As the magnetic field strength increases, reluctance?

Detailed Solution for Test: Reluctance - Question 8

Reluctance is directly proportional to the strength of magnetic field, hence as the strength of magnetic field increases, the reluctance increases.

Test: Reluctance - Question 9

As the magnetic flux density increases, the reluctance _____________

Detailed Solution for Test: Reluctance - Question 9

Reluctance is inversely proportional to the magnetic flux density, hence as magnetic flux density increases, reluctance decreases.

Test: Reluctance - Question 10

Calculate the reluctance when the magnetomotive force is 10A turns and the flux is 5Wb.

Detailed Solution for Test: Reluctance - Question 10

We know that:
F=phi*S
Substituting the given values from the question:
S=2A/Wb.
