The constant L for a single coil is called its:
ASelf inductance
BMutual induction
CMagnetic charge
DInduced current
Answer & Solution
Correct answer: A. Self inductance
1. A coil's own changing current changes its own flux.
2. The proportionality constant is written L.
3. L is called the self-inductance of the coil.
4. So the answer is self inductance.
