Question

Which of the following factors is the self-inductance associated with a coil independent of?

• A. induced voltage
• B. current
• C. time
• D. coil resistance

Hint:

Self-inductance is a function of the physical properties of the coil and is independent of the current.

Answer 1

The Correct Option is B

Step 1: Understanding Self-Inductance 
Self-inductance is a property of a coil that quantifies its ability to resist changes in current.
The self-inductance \( L \) of a coil is determined by its physical properties, such as the number of turns, the area of the coil, the length of the coil, and the permeability of the material inside the coil. 
Step 2: Why Other Options Are Incorrect 
Option (a) is incorrect because the induced voltage is related to the rate of change of current, which affects the self-inductance.
Option (c) is incorrect because the self-inductance depends on the time rate of change of current.
Option (d) is incorrect because coil resistance does affect the efficiency of energy transfer but not the self-inductance. 
Step 3: Conclusion Thus, the self-inductance of a coil is independent of the current flowing through it.
