Directions : In the following questions, A statement of Assertion (A)...
Assertion (A): Principle of operation of AC generator is electromagnetic induction.
Reason (R): Resistance offered by inductor for AC is zero.
The correct answer is option B. Both A and R are true but R is not the correct explanation of A.
Explanation:
The principle of operation of an AC generator is indeed electromagnetic induction. Let's break down the statement and reason to understand why option B is correct.
Principle of Operation of AC Generator:
An AC generator, also known as an alternator, is a device that converts mechanical energy into electrical energy. It works on the principle of electromagnetic induction, which states that when a conductor is moved in a magnetic field, an electromotive force (EMF) is induced in the conductor.
The AC generator consists of a rotor (rotating part) and a stator (stationary part). The rotor is an electromagnet that rotates within a stationary magnetic field produced by the stator. As the rotor spins, the magnetic field lines cut across the conductors present in the rotor, inducing an alternating current (AC) in these conductors.
The AC generator utilizes the phenomenon of electromagnetic induction to produce an alternating current. Therefore, assertion A is true.
Resistance offered by an Inductor for AC:
An inductor is a passive electrical component that stores energy in a magnetic field when an electric current flows through it. It is characterized by its inductance, which is the property that opposes any change in the current flowing through it.
In the case of an AC circuit, the inductor does offer some resistance to the flow of current due to its inductance. This resistance is known as inductive reactance and is measured in ohms.
Therefore, reason R is false as the resistance offered by an inductor for AC is not zero.
Conclusion:
Both the assertion and reason provided in the question are true. However, reason R is not the correct explanation of assertion A. The principle of operation of an AC generator is electromagnetic induction, but the resistance offered by an inductor for AC is not zero. Hence, option B is the correct answer.
Reason (R): Resistance offered by inductor for AC is zero.
The correct answer is option B. Both A and R are true but R is not the correct explanation of A.

Directions : In the following questions, A statement of Assertion (A)...
Principle of operation of AC generator is electromagnetic induction. The assertion is true. Resistance offered by inductor = 2πfL. For AC, f ≠ 0. So, 2πfL ≠ 0. So, the reason is false.
