What you will learn

 

How do I solve circuits with inductors?

 

How do I find the initial and final values for current in an inductor circuit?

 

What is a time constant?

 

How do I calculate the time constant for a resistor-inductor circuit?

Description

Day 26 of Linear Circuits.  Inductors are one of the three passive circuit components (along with resistors and capacitors).  However, their operation and behavior is often shrouded in mystery.  After seeing what inductors are and how they work in our previous lecture, today, we will see how we can always find the initial and final values for resistor-inductor circuits’ currents and voltages AND specify their entire behavior by just one variable — the time constant, TAU.

 

The material covers all of the lecture material from an twenty-sixth lecture in a traditional, sophomore-level linear circuits class.
