List I | List II | ||
A | AC generator | i | Presence of both L and C |
B | Transformer | ii | Electromagnetic Induction |
C | Resonance phenomenon to occur | iii | Quality factor |
D | Sharpness of resonance | iv | Mutual Induction |
Based on fundamental electrical engineering concepts:
- An AC generator operates on Electromagnetic Induction (II).
- A Transformer operates based on Mutual Inductance (IV).
- Resonance phenomenon occurs due to Presence of both L and C (I).
- Sharpness of Resonance is linked to Quality Factor(III).
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : If oxygen ion (O\(^{-2}\)) and Hydrogen ion (H\(^{+}\)) enter normal to the magnetic field with equal momentum, then the path of O\(^{-2}\) ion has a smaller curvature than that of H\(^{+}\).
Reason R : A proton with same linear momentum as an electron will form a path of smaller radius of curvature on entering a uniform magnetic field perpendicularly.
In the light of the above statements, choose the correct answer from the options given below
Match List-I with List-II.
Choose the correct answer from the options given below :
Magnets are used in many devices like electric bells, telephones, radio, loudspeakers, motors, fans, screwdrivers, lifting heavy iron loads, super-fast trains, especially in foreign countries, refrigerators, etc.
Magnetite is the world’s first magnet. This is also called a natural magnet. Though magnets occur naturally, we can also impart magnetic properties to a substance. It would be an artificial magnet in that case.
