Electro Magnetic Induction And Alternating Currents Question 297
Question: Assertion : An ac generator is based on the phenomenon of self-induction. Reason : In single coil, we consider self-induction only.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.

Answer:
Correct Answer: E
Solution:
ac generator is based on the principle of the electromagnetic induction. When a coil is rotated about an axis perpendicular to the direction of uniform magnetic field, an induced emf is produced across it.
