JEE Mains · Physics · STD 12 -6. Electromagnetic induction
Regarding self-inductance:
A. The self-inductance of the coil depends on its geometry.
B. Self-inductance does not depend on the permeability of the medium.
C. Self-induced e.m.f. opposes any change in the current in a circuit.
D. Self-inductance is electromagnetic analogue of mass in mechanics.
E. Work needs to be done against self-induced e.m.f. in establishing the current.
Choose the correct answer from the options given below:
- A \(\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{E}\) only
- B B, C, D, E only
- C \(\mathrm{A}, \mathrm{C}, \mathrm{D}, \mathrm{E}\) only
- D A, B, C, D only
Answer & Solution
Correct Answer
(C) \(\mathrm{A}, \mathrm{C}, \mathrm{D}, \mathrm{E}\) only
Step-by-step Solution
Detailed explanation
A. The self-inductance of the coil depends on its geometry. This is true because the self-inductance of a coil is given by formulas that include its geometrical parameters (number of turns, cross-sectional area, length, etc.). For example, for a solenoid,…
