The ratio of average induced emf to the rate of change of current in the coil is called
Correct answer: A. Self inductance
- A. Self inductance
- B. Mutual inductance
- C. Self induction
- D. Mutual induction
Explanation
A is the correct answer. The ratio of the average induced emf to the rate of change of current in the coil is known as self inductance. It is denoted by the symbol L and is measured in henrys (H).

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
