LESSON DESCRIPTION: This lesson defines inductance; expresses the relationship between
a changing current
in a conductor and the magnetic field surrounding the conductor; defines Len's Law; describes inductors;
introduces symbols related to inductance; describes mutual inductance; introduces mathematical equations to
calculate unknowns; and presents problems for the student to solve.
TERMINAL LEARNING OBJECTIVE:
You will select statements which describe or answer questions concerning inductance,
the relationship existing between current in a conductor and the surrounding magnetic
field, Len's law, mutual inductance, and factors affecting inductance. Additionally you will
solve for the time-constant of simple RL circuits.
You will have this subcourse booklet for self-paced study. All information required is
To demonstrate competency of this task, you must achieve a minimum score of 70% on
the subcourse examination.
