Question 1 of 8
1. Question
1 pointsInductor blocks ……………………. in an electrical circuit.
Correct
Incorrect

Question 2 of 8
2. Question
1 pointsWhich of the electrical quantity cannot change in an inductor instantly?
Correct
Incorrect

Question 3 of 8
3. Question
1 pointsThe inductive coil in an electrical circuit stores the energy in the form of ……………………….
Correct
Incorrect

Question 4 of 8
4. Question
1 pointsThe voltage in an electrical circuit which consists of single inductive coil ………….
Correct
Incorrect

Question 5 of 8
5. Question
1 pointsGroup of wires are wounded as coil, if the wires in the coil are moved closer then the inductance of a coil ………………..
Correct
Incorrect

Question 6 of 8
6. Question
1 pointsAn ideal inductor is placed in an electrical circuit which is excited by a dc power supply source. What is the equivalent circuit of inductor in the circuit?
Correct
Incorrect
Answer : Short circuit
Explanation :
Inductive reactance (X_{L})= 2πfL
for dc power supply f = 0
so X_{L} = 0 .
so it offers zero resistance i.e. short circuit. 
Question 7 of 8
7. Question
1 pointsinductor in an electrical circuit is also called as …………………..
Correct
Incorrect

Question 8 of 8
8. Question
1 pointsIf the number of turns in an inductive coil is reduced, the inductance of that coil will ………………..
Correct
Incorrect
Answer : Decrease
Explanation :
Inductance L is proportional to (coil turns ) ^{2}
So if the turns decreases the inductance also decreases.
